High Frequency Thyristor KA 300A – 2500A

Ultra Fast High Frequency Thyristor KA series AS ENERGITM in disc design is a press pack type ultra fast turn-off high frequency semiconductor device. High frequncy 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 1200A at frequency range is up to 20kHz in circuits with voltages to 2400V (depending on series).

The anode and cathode of the high frequency thyristor (polarity) are determined by the symbol on the case. A special feature of high frequency thyristors is their highly branched control electrode that ensures short propagation time of the onstate.

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.

High frequency thyristors can be manufactured for use in temperate, cold and tropical climates. Fast 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.

Series (ratings) thyristors are: KA300A, KA400A, KA500A, KA600A, KA700A, KA800A, KA900A, KA1000A, KA1100A, KA1200A, KA1400A, KA1500A, KA1700A, KA2000A, KA2500A.

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".

I'm Gizem, I'm a chemical engineer. I'm interested in making ceramic stuffs as a hobby. Would you please give some explanation about my questions below;
1) If I only mix SiO2 and Fe2O3 (3:1), can i get a suitable product without using other components?
2) Can i use water as fastener? or would you suggest me another fastener?
3) At which temperature should i mix them?
Thank you for your interest, Kind Regards

Hello, Gizem. The mass of ceramic is produced by grinding and mixing with water of different components: clay, feldspar, sand, kaolin. The proportions of these materials are different percentages, depending on what and with what characteristics you need to get a ceramic mass.
Each manufacturer of ceramic mass has its own recipes and its own raw materials, which are available in its region.
There are also books on ceramics that specify the chemical composition and approximate recipes for ceramic masses.
