Point-of-use surge protection consists of a power strip with surge protection circuitry incorporated. It should be used to protect expensive electrical equipment, such as equipment in home entertainment centers and home offices. Better point-of-use surge protectors provide visual indication that the surge protection circuitry is still functioning and protecting the connected equipment. A whole-house protection plan using both point-of-use and point-of-entry surge protectors is needed to guard against surges from both inside and outside the home.

2011 TSMC open innovation Platform
Applications like motor control, power management and conversion, LCD panel drivers and automotive systems require IC interfaces that can tolerate and drive high voltages (10V to 100V). Moreover, in most of these applications the ICs are operated in harsh environments (high temperature, high current/voltage transient disturbance), close to the boundaries of the IC technology. Further, to reduce the Bill of Materials (BOM) system makers are constantly shifting requirements that were once a system/PCB issue to the IC makers. IC makers designing high voltage applications need robust and reliable technology that can meet a growing set of requirements.
Based on TSMC’s comprehensive BCD technology platform in 0.25um and 0.18um, Sofics has developed novel EOS/ESD protection devices that can solve those needs.
This paper first presents an overview of the EOS, ESD, latch-up and other requirements that IC makers face today. Secondly the TSMC BCD technology that was used as the verification platform is touched upon. Finally analysis results and on-going product implementations are shown on 0.25um BCD and 0.18um BCD technology. The unique BCD ESD solutions are available for TSMC foundry customers at a fraction of the development cost.

Residential Surge Protection 3
1. Point-of-Use Surge Protection

for example, include television sets, stereo equipment, DVD

Point of Use
Surge Protector
29
2. Home Office Today, millions of homes have home offices. Home offices
include computers, fax machines, printers, copiers, scanners,
and telephones. Home offices will benefit significantly from
point-of-use surge protection, since the replacement cost of
equipment is high. Home offices are frequently associated
with a home business. The expense of lost business while
equipment is down can be significant.
Point-of-Use
Surge Protection
Basic Power Strips Too often, home owners seek inexpensive solutions to
connecting and protecting expensive equipment. Inexpensive
extension cords, add-on outlets, and basic power strips
provide no surge protection, leaving equipment susceptible to
performance degradation and damage.
30
3. Basic Surge Protection Home owners may also settle for an inexpensive surge
protected power strip. Some of these may have a fuse or
miniature circuit breaker that can be reset, but provide no visual
indication that the surge protection circuitry is functioning. A
home owner may think the connected equipment is protected,
when in reality it is not.
Visual Indication Good point-of-use surge protectors, like good point-of-entry
surge protectors, will sacrifice themselves and not the
connected equipment in the event of a catastrophic surge. It is
important to note that in many point-of-use surge protectors,
the electrical outlets continue to supply power to equipment
even though the surge protection circuitry may have been
damaged. Better point-of-use surge protection devices provide
visual indication that the surge protection circuitry is functional
and protecting the connected equipment.
31
4. Other Features In addition, better point-of-use surge protectors are designed
around the equipment they are intended to protect. Equipment
is just as susceptible to damage from electrical surges on
telephone and cable feeds as from the electrical power supply.
Point-of-use surge protectors designed for use with home
entertainment equipment should include surge protection
circuitry for cable or satellite connections. Surge protection
intended for use in the home office should include connections
for a telephone, fax, and modem.

TVSS Point-of-use surge protectors are classified as transient voltage
surge suppressors (TVSS) according to NEC® Article 285.21
requirements because they are installed on the load side of the
service disconnect overcurrent protection. Point-of-use surge
protectors should be UL 1449 listed.

7. Whole-House Protection
Surge Protection Plan No single product can protect equipment in a residence from
all electrical surges. In this section we will learn how a tiered
protection plan, consisting of point-of-use and point-of-entry
surge protectors, help guard against disturbances from inside
and outside the home.
Point-of-Use Surge Protection
Point-of-Entry Surge Protection
35
8. Point-of Entry Protection We have already learned that point-of-entry protectors can
is not Enough prevent electrical surges on the utility service from entering
the home. Electrical surges can come from a lightning strike on
or near high-voltage transmission lines or switching of primary
circuits by local utilities.

Surges from Within However, point-of-entry surge protectors are not whole-house
the Home protectors. Point-of-entry surge protectors cannot eliminate all
electrical surges developed within the home. For example, an
air conditioner can cause a small electrical surge every time
it cycles on and off. Surges caused by equipment within the
home are usually weaker than surges caused by lightning,
however, they occur more frequently. These surges are
distributed throughout the home’s electrical system, possibly
causing problems with other connected equipment.

and swimming pool filtration equipment are just a few
examples of outdoor appliances in use today.

10. Surges from Most damage occurs from electrical surges that enter the home
Other Services from outside services. We have already learned how lightning
strikes can enter the home through the electrical utility. It is
equally important to note that telecommunication and cable
services can also conduct electrical surges into the home
causing damage to televisions, modems, and telephones.
The National Electrical Code® requires services to be grounded
and bonded together. The purpose is to reduce fire and shock
hazard in the event electric utility power conductors come in
contact with communication conductors.
However, this will not protect sensitive electrical and electronic
equipment located within the house.

38
11. Adding Point-of-Use The addition of appropriate point-of-use surge protectors
adds protection to equipment such as computers, home
entertainment systems, and telecommunications equipment.
These systems would otherwise be vulnerable to surges
caused by:
• surges caused by lightning entering the home through
unprotected underground wiring.
• surges from cable or telecommunication systems.
• switching, such as an air conditioner or other home
electrical equipment.

Load Center
Point-of-Use Protection Homeowners often mistakenly think that point-of-use surge
is not Enough protection is sufficient and forgo the extra expense of point-of-
entry surge protection. It is impractical to connect point-of-use
surge protectors at every outlet to protect appliances such as
washing machines, dryers, dishwashers, stoves, ovens, garage
door openers, air conditioners, and heaters. Some appliances
are hard wired and may require a qualified electrician to install a
surge protector.
39
12. Surge Current Point-of-entry surge protectors are generally more robust and
able to withstand higher values of surge current. A nearby
lightning strike, for example, can result in surge current as high
as 10,000 amps at the point-of-entry. Siemens QP and TVSS
circuit breaker, installed in a Siemens load center can withstand
a current impulse as high as 40,000 amps. Siemens Primax®
point-of-entry protector can withstand a current impulse as high
as 60,000 amps.
Although some point-of-use surge protectors are also capable
of handling larger surge currents, it is much better to shunt this
high current to ground before it enters the distribution system.
In addition, many appliances may not be connected to a point-
of-use surge protector.
Clamping Voltage Another advantage to using a tiered system is the ability of
point-of-entry surge protectors to reduce surge voltage at the
service entrance. Primax point-of-entry surge protectors, for
example, have a clamping voltage of 400 volts. An initial 2500
volt surge from a lightning strike would be clamped to 400 volts
at the point of entry. Reducing voltage and corresponding surge
current makes it easier for point-of-use surge protectors, which
have a UL 1449 maximum clamping voltage of 330 volts, to
handle the overvoltage. In addition, an extra layer of protection
to sensitive and expensive electronic equipment is provided.
