1. What is the working principle of a single rectifier diode?
A rectifier diode conducts current when forward biased, converting the positive half wave of alternating current into direct current. When reverse biased, the diode blocks the current, thereby preventing the negative half wave from passing through and achieving rectification effect.
-
2. How to choose the appropriate rectifier diode?
When making a choice, the following factors need to be considered:
Current capacity: Determine the maximum current that the diode needs to handle.
Reverse voltage: Ensure that the reverse voltage of the diode can withstand the highest voltage in the circuit.
Forward voltage drop: A lower forward voltage drop can improve circuit efficiency.
Recovery time: For high-frequency applications, choose fast recovery or Schottky diodes. -
3. 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.

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.
