1. What is forward voltage drop?
Forward voltage drop refers to the voltage drop generated when the current passes through a diode when it is conducting. The forward voltage drop of silicon rectifier diodes is usually around 0.7V, while the forward voltage drop of Schottky diodes is usually lower, between 0.2V and 0.3V.

2. What is a fast recovery diode?
Fast recovery diode is a special type of rectifier diode with a short reverse recovery time, suitable for high-frequency power supplies and switch mode power supplies (SMPS) applications, reducing switching losses.

3. What is the difference between Schottky diodes and traditional silicon rectifier diodes?
Schottky diodes have a lower forward voltage drop (typically 0.2V to 0.3V) and faster switching speed, making them suitable for high-frequency applications. However, their reverse voltage is relatively low and is typically used in circuits with lower voltages.

4. How to determine if the rectifier diode is damaged?
Use a multimeter to measure the forward and reverse resistance of a diode. If the diode exhibits low impedance or high impedance in both directions, it may have been damaged. Under normal circumstances, there should be low impedance when conducting in the forward direction, and high impedance when conducting in the reverse direction.
