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. Can a single rectifier diode be used for high-frequency applications?
Traditional silicon rectifier diodes are not suitable for high-frequency applications because their reverse recovery time is relatively long. For high-frequency applications, fast recovery diodes or Schottky diodes are typically used to reduce switching losses and improve efficiency.
