The document describes a series of transient voltage suppressor (TVS) diodes called the 5KP series. The diodes are designed to protect electronic equipment from voltage transients caused by lightning or other events. They have features like fast response time, low clamping voltage, and high temperature tolerance. The document provides detailed electrical characteristics and ratings for each diode model in the 5KP series, including reverse standoff voltage, maximum clamping voltage, peak pulse current, and more. Curves show specifications for pulse power rating, derating, junction capacitance, and non-repetitive surge current.
