Frequently Asked Questions (FAQs)

1. What is switching diode and its characteristics?

Switching Diodes are a type of semiconductor diode. They are specially designed and manufactured for "on" and "off" on a circuit. ... This diode has the performance of passing current (ON) when voltage is applied in the forward direction and stopping (OFF) current when the voltage is applied in the reverse direction.

2. What are the applications of switching diode?

Switching Diode Applications Voltage clamping, High speed rectifying and switching circuits, Reverse current and discharge protection, Switched-mode power supplies (as a rectifier).

3. How does a diode act as a switch?

Whenever a specified voltage is exceeded, the diode resistance gets increased, making the diode reverse biased and it acts as an open switch. Whenever the voltage applied is below the reference voltage, the diode resistance gets decreased, making the diode forward biased, and it acts as a closed switch.
