Rectifier diodes.
Rectifier diodes.
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.

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.

Thyristors are used in DC and AC converters with an operating frequency of up to 1,000 Hz, in inverting and switching circuits of converter setups for electric locomotives and other types of electrically propelled vehicles, in power rectifiers for electroplating baths, for charging batteries, in high-voltage rectifier-inverter units of DC transmission line substations, and in aircraft de-icing equipment.
