Purpose of switching diode — SUNMATE

The time of switching diode from off (high resistance state) to on (low resistance state) is called on time; The time from continuity to deadline is called reverse recovery time; The sum of the two times is called switching time. Generally, the reverse recovery time is greater than the opening time, so only the reverse recovery time is given in the operating parameters of the switching diode. The switching speed of switching diode is quite fast. For example, the reverse recovery time of silicon switching diode is only a few nanoseconds, and even germanium switching diode is only a few hundred nanoseconds

The switching diode is characterized by fast switching speed, small size and high reliability.

Widely used in switching circuits, detection circuits, high-frequency and pulse rectification circuits and automatic control circuits of electronic equipment
