Fast Thyristor KK 200A – 4800A
Fast Thyristor KK series AS ENERGITM in disc design is a press pack type fast switching semiconductor device. Fast thyristors meet requirements, such as increased di/dt resistance, low switching losses, short turn-on and turn-off time. Regulating and converting DC and AC currents to 4800A at frequency range is up to 10kHz in circuits with voltages to 4800V (depending on series).
The anode and cathode of the fast 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.
Fast thyristors can be manufactured for use in temperate, cold and tropical climates. Fast thyristors of the disc type KK are used in various power converters (e.g. melting furnaces) where fast switching and control of currents is necessary.
Series (ratings) thyristors are: KK200A, KK300A, KK400A, KK500A, KK600A, KK700A, KK800A, KK1000A, KK1200A, KK1300A, KK1500A, KK1600A, KK1700A, KK1800A, KK1900A, KK2000A, KK2100A, KK2200A, KK2400A, KK2500A, KK2600A, KK2700A, KK2900A, KK3000A, KK3200A, KK3300A, KK3600A, KK3900A, KK4000A, KK4200A, KK4300A, KK4400A, KK4800A.
Specifications and parameters, datasheets PDF, dimensions, drawings, case diagrams thyristors, recommended coolers are listed below.
Our company provides a quality guarantee for fast thyristors KK of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide technical passport and certificate of conformity.
The final price for fast disc thyristors KK depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.

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".
