1. What is the maximum reverse voltage (PIV) of a rectifier diode?
The Peak Inverse Voltage (PIV) is the maximum reverse voltage that a diode can withstand. When selecting a diode, the PIV must be higher than the maximum reverse voltage in the circuit, usually twice or more the input voltage.
-
2. 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.
-
3. How to identify the polarity of a single rectifier diode?
Rectifying diodes usually have polarity markings, with the positive (anode) of the diode being "+" and the negative (cathode) being "-". On the packaging of diodes, there is usually a circular mark on the cathode side indicating the direction of the diode.

4. How to improve the efficiency of rectifier diodes?
The use of Schottky diodes or fast recovery diodes can reduce forward voltage drop and reverse recovery time, thereby improving the efficiency of rectifier circuits, especially in high-frequency applications.
