Fast thyristors are used in static power converters, and in various DC and AC power units with a frequency of up to 5,000 Hz, where short on/off switching intervals are required; in various types of electric welding equipment, in frequency converters for electrothermics, in traction systems of electric locomotives and electrified urban transport vehicles, in air ozonizers, in generators, and in modulators.

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.
