Phase control thyristors KP3900A-(18...22) are general purpose power disc thyristors, also known as Silicon Controlled Rectifier (SCR). They are designed to convert and control DC and AC currents up to 3900A with frequency up to 500Hz in circuits with voltages up to 1800V – 2200V (voltage class from 18 to 22). Thyristor dimensions ØDxØdxH – 120x84x26.5 mm (outer case diameter X contact surface diameter X case height), weight – 1.4 kg.
Thyristor ratings: KP3900A 1800V, KP3900A 2000V, KP3900A 2200V.
The anode and cathode of the thyristor (polarity) are determined by the symbol on the case.
For cooling during the operation of power thyristors they are mounted with coolers (heat sinks). Depending on the amount of heat generated and the working conditions of the semiconductors, either natural air flow cooling or forced cooling can be used.
When assembling, the necessary clamping force Fm specific for each type of thyristor package (indicated in the parameter table) must be provided.
Thyristors can be manufactured for use in temperate, cold and tropical climates. Thyristors of the disc type KP are used in various power converters (e.g. melting furnaces) where fast switching and control of currents is necessary.

Heat sinks for power disc thyristors:
Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc design.
Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.
See for more information about coolers "Air-heatsink" and "Water-heatsink".
