- 3. Welcome and thank you for joining my presentation on power diodes. We will explore the constructional and working differences between three common types of power diodes: General Purpose, Fast Recovery, and Schottky. INTRODUCTION
- 4. GENERAL PURPOSE DIODE Composed of a P-N junction with a single semiconductor material. CONSTRUCTION: Designed for general rectification and switching applications, with moderate switching speed. WORKING: APPLICATION: Composed of a P-N junction with a single semiconductor material.
- 5. FAST RECOVERY DIODE Utilizes special epitaxial layers to reduce recovery time. CONSTRUCTION: Designed for faster switching by minimizing reverse recovery time. WORKING: APPLICATION: Ideal for high-frequency applications, such as switching power supplies and inverters.
- 6. SCHOTTKY DIODE Combines a metal and semiconductor junction, resulting in lower voltage drop. CONSTRUCTION: Offers very fast switching speed and lower forward voltage drop. WORKING: APPLICATION: Used in high-speed rectification, voltage clamping, and high-frequency RF applications.
- 7. Schottky Fast Recovery General Purpose Fast Recovery diodes have additional layers to reduce recovery time. Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Schottky diodes have a metal- semiconductor junction, reducing voltage drop.
- 8. Schottky Fast Recovery General Purpose Fast Recovery diodes minimize reverse recovery time for faster switching. Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Sed non orci hendrerit augue interdum lacinia at egestas dolor. Vivamus elementum pulvinar tempus. Working Differences General Purpose diodes offer moderate switching speed. Schottky diodes provide very fast switching and low forward voltage drop.
- 9. COMPARISON General Purpose diodes are versatile but have moderate performance and exhibit standard forward voltage drops. GENERAL PURPOSE Fast Recovery diodes are optimized for speed, reducing reverse recovery time, but may have slightly higher forward voltage drops compared to General Purpose diodes. FAST RECOVERY Schottky diodes excel in high-speed applications with their ultra-low forward voltage drop, but they have limited reverse voltage capabilities. SCHOTTKY
- 10. CONCLUSION General Purpose, Fast Recovery, and Schottky diodes serve different purposes. Constructional and working differences make each diode suitable for specific applications. Careful diode selection is crucial for efficient electronic circuit design.
