What is a switching diode used for?
A switching diode is suitable for switching a small signal of up to 100 mA, acting as a rectifier. In contrast, a rectifier diode is used for AC line rectification (from alternating current to direct current). Switching diodes are designed to handle a voltage of less than tens of volts.
Which diodes provides high reverse breakdown voltage?
Unlike standard diodes that are employed in the forward direction, Zener diodes are designed to be used in the reverse direction. The reverse breakdown voltage of a Zener diode is referred to as the Zener voltage VZ, and the current value at this time is called the Zener current (IZ).
What is an important characteristic of a Schottky diode as compared to an ordinary silicon diode when used as a power supply rectifier?
An important characteristic of a Schottky diode as compared to an ordinary silicon diode when used as a power supply rectifier is that it has less forward voltage drop.
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.
What is switching characteristics of diode?
The switching diode behaves as a short circuited for an instance in reverse direction. The minority carriers will cross the junction and conduct the current, which is called as Reverse Saturation Current. The following graph represents the condition during reverse bias.
What diode has the lowest voltage drop?
Germanium diodes have lower voltage drop than silicon diodes. Forward voltage drop for germanium is around 0.3 volt. Germanium diodes are mostly used as low level signal detectors.
