Voltage suppressors are rectifier avalanche diodes that dissipate power pulse in the breakdown region of the reverse volt-ampere curve within a limited period of time. They are used for protection of semiconductor power devices and capacitors from switching surges, as well as to limit voltage in electrical equipment at frequencies up to 500 Hz.

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.

Fast distributed gate thyristors and fast strong distributed gate thyristors (high-speed pulse thyristors) are used in oscillators, modulators, inverters, and electric drive systems with thyristor-controlled pulse control with frequency of up to 20,000 Hz, where pulse operating currents, short on/off switching intervals, and high rates of current build-up are primarily required. The thyristors are characterized by high current-carrying capacity at high frequencies.
