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 a single rectifier diode and a bridge rectifier?
A single rectifier diode can only rectify the positive half wave of AC power (half wave rectification), while a bridge rectifier composed of four diodes can rectify the positive and negative half waves of AC power (full wave rectification), with higher efficiency and smoother output.

3. 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.
-
4. 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.
