Avalanche Diodes.
Avalanche Diodes.
Avalanche diodes are rectifier diodes with controlled avalanching allowing power pulse to dissipate in the breakdown region of the reverse volt-ampere curve within a limited period of time.
These diodes are used in DC and AC circuits with frequency of up to 500 Hz, and in general purpose electrical and electronic devices.
Avalanche diodes can eliminate or considerably simplify overvoltage protection circuits in converters, especially in case of a large number of series connected diodes.

Avalanche thyristors are used in static power converters and in other DC and AC circuits with a frequency of up to 1,000 Hz. Under certain conditions of reverse voltages, they can be used without any additional protection measures.

The fast recovery diodes are used in static power converters and electronic devices, as well as in other DC and AC circuits of various power units, where the specific intervals of reverse recovery and low recovery charges are primarily required.
These diodes can also be used as freewheeling diodes connected back-to-back/parallel to thyristors or as shunting diodes for inductance load.
