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 are the common applications of a single rectifier diode?
They are commonly used in power circuits, chargers, AC to DC converters, motor drives, circuit protection, and other electronic devices to convert AC power to DC power or protect circuits from reverse current.
-
3. 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.

4. 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.
