Phase Control Thyristor KP 300A – 6800A
Phase control thyristors KP series AS ENERGITM are general purpose power disc thyristors. They are designed to convert and control DC and AC currents up to 6800A with frequency up to 500Hz in circuits with voltages up to 600V - 6500V (voltage class 6 to 65).
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.
Series (ratings) thyristors are: KP300A, KP400A, KP500A, KP600A, KP700A, KP800A, KP900A, KP1000A, KP1200A, KP1300A, KP1400A, KP1500A, KP1700A, KP1800A, KP1900A, KP2000A, KP2100A, KP2400A, KP2500A, KP2600A, KP2700A, KP2800A, KP3000A, KP3200A, KP3300A, KP3400A, KP3900A, KP4200A, KP4300A, KP4600A, KP5200A, KP5700A, KP6800A.

High Power Semiconductors by AS ENERGI
Our company is engaged in the manufacturer and sale of power semiconductors (power thyristors, diodes, modules).
You can buy thyristors from us in any volumes, and when ordering large lots, the price will be lower.
We have earned the trust of customers and supply products all over the world.
For questions regarding the acquisition of High Power Thyristors, Diodes, send an email request to:
And we will provide you a commercial offer for delivery.
For a large number, we will provide an individual price!!!
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".
