This is 85V, 200mA, Silicon Switching Diode, Rectifier.

Advantages Vs Disadvantages


1. High-speed switching: Fast switching due to its low reverse recovery time and low capacitance

2. Low forward voltage drop: The low forward voltage drop reduces power dissipation and improves circuit efficiency

3. Small size: The small size makes it ideal for use in space-constrained applications

4. Wide operating temperature range: Operate in a wide range of temperatures, making it suitable for use in harsh environments


1. Low reverse voltage rating: Maximum reverse voltage rating of 85V, which may limit its use in high-voltage applications

2. Low current handling: It is designed for low current applications and may not be suitable for high current requirements

3. Limited reverse recovery capability: It has a limited reverse recovery capability and may not be suitable for applications with high di/dt rates

Q1: What is the difference between a Schottky diode and a regular diode?
A1: A Schottky diode has a lower forward voltage drop than a regular diode, which makes it useful in applications where power dissipation is a concern. Schottky diodes also have a faster switching speed and lower reverse recovery time.

Q2: What is reverse recovery time?
A2: Reverse recovery time is the time it takes for a diode to switch from conducting in the forward direction to blocking in the reverse direction. This time delay can cause issues in high-frequency switching applications, which is why Schottky diodes are often used instead.
