Fast Switching Thyristor TFI373-2000 AS ENERGITM in disc design is a press pack type fast switching (pulse) semiconductor device. This fast pulse power thyristor designed for converting and control DC and AC currents up to 2000A with frequency up to 10kHz in circuits with voltages up to 2000V – 2500V (voltage class from 20 to 25). Thyristor dimensions ØDxØdxH – 112x75x35 mm (outer case diameter X contact surface diameter X case height), weight – 1700 g.

Fast switching 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 higher frequencies modes (up to 10kHz). 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 switching 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 switching thyristors 1700A, 1800A, 1900A, 2000 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 case (indicated in the parameter table) must be provided.

Specifications and parameters, datasheets PDF, sample technical passport, dimensions, outline drawings, case diagrams thyristors, recommended coolers are listed below.

Our company provides a quality guarantee for power fast thyristors of 2 years from the date of purchase. When supplying pulse thyristors, if necessary, we provide technical passport, certificate of conformity.

Fast switching thyristor ratings: TFI373-2000-20 (2000A 2000V), TFI373-2000-22 (2000A 2200V), TFI373-2000-24 (2000A 2400V), TFI373-2000-25 (2000A 2600V).

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.

Is It need to apply vaselin or thermal past at Thyristor surfaces then attach to radiator/current leading parts?
Maksim 27.06.2022 at 10:39

When assembling thyristors, diodes with heat sinks, it is recommended to lubricate the contact surfaces with a thin layer of heat conducting paste to improve the heat transfer parameters. But this is not a prerequisite for assembly.
