Switching diode operating characteristics

Switching diode operating characteristics

The time from the cut-off (high resistance state) to the conduction (low resistance state) of the Switching diode is called the turning on time; The time from conduction to cut-off is called reverse recovery time; The sum of two times is called the switching time. Generally, the reverse recovery time is greater than the opening time, so only the reverse recovery time is given in the usage parameters of the Switching diode. The switching speed of Switching diode is quite fast, like the reverse recovery time of silicon switching diodes, which is only a few nanoseconds, and even germanium switching diodes, which are only a few hundred nanoseconds.

Switching diode have the characteristics of fast switching speed, small size, long service life, and high reliability, and are widely used in switching circuits, detection circuits, high-frequency and pulse rectification circuits, and automatic control circuits of electronic equipment.
