The diodes are used in DC and AC circuits with frequency of up to 500 Hz, in general purpose electrical and electronic devices, in low voltage rectifiers for welding and electroplating equipment, in the electrotechnical equipment of ships, in converters of electrically propelled vehicles, and in power supplies of machine tools and automatic production lines.

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.
