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. 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.
-
3. 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.

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.
