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 reverse recovery time of a rectifier diode?
Reverse recovery time refers to the time required for a diode to transition from a forward conducting state to a reverse blocking state. A shorter reverse recovery time is particularly important in high-frequency applications to reduce power loss.
-
3. 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.

4. What are the packaging types of rectifier diodes?
There are various packaging types for rectifier diodes, including axial pin packaging (such as DO-41), surface mount packaging (such as SMA, SMB), and high-power packaging (such as TO-220). When selecting, the appropriate packaging should be chosen based on the application's heat dissipation requirements and installation method.
