Ultra Fast High Frequency Thyristor KA1000-(12…16) JY FACTORY in disc design is a press pack type ultra fast turn-off high frequency semiconductor device. This high frequency thyristor designed for converting and control DC and AC currents up to 1000A with frequency up to 20kHz in circuits with voltages up to 1200V – 1600V (voltage class from 12 to 16).

Thyristor dimensions ØDxØdxH – 69x45x26 mm (outer case diameter X contact surface diameter X case height), weight – 370 g. KA-series Fast High Frequency thyristors are devices with reduced tq, trr, Qrr values and with a higher value (diT/dt)cr (up to 2500 A/µs) designed to operate at high frequencies modes (up to 20kHz). A special feature of such thyristors is their highly branched control electrode that ensures short propagation time of the onstate.

Fast thyristors are characterized with a very low turn-off time that sets them apart from the standard models. They are used in welding, induction heating and melting, electric transportation, AC drives, UPS, and other systems requiring short turn-on and turn-off times.

The thyristors have an industry-standard ceramic sealed housing isolating the functional part and the semiconductor element from mechanical impacts and environment. The anode and cathode of the thyristor (polarity) are determined by the symbol on the case. Fast thyristors are in a press pack disc (capsule, tablet) housing.

This fast thyristor can be an alternative product, replacement, analog, equivalent for other types of fast thyristors 980A, 990A, 1000 amp in a disk package. 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 KA are used in various power converters (e.g. melting furnaces) where fast switching and control of currents is necessary. Specifications and parameters, datasheets PDF, dimensions, drawings, case diagrams thyristors, recommended coolers are listed below.

Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide technical passport and certificate of conformity. Fast thyristor ratings: KA1000A 1200V, KA1000A 1400V, KA1000A 1600V.

The final price for disc fast high frequency thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
