Fast Switching Thyristor TFI361-100 AS ENERGITM in stud is a fast switching semiconductor device, designed for converting and control DC and AC currents up to 100A with frequency up to 10kHz in circuits with voltages up to 600V – 1200V (voltage class from 6 to 12). Thyristor package type – ST6, mounting standard thread M20x1.5, (on request, UNF thread 3/4"-16UNF-2A), weight – 240 g.
Fast switching (pulse) 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). The thyristor parameters of VTM, tq, Qrr are interconnected, so a decrease in the value of tq and Qrr leads to an increase in VTM. Fast switching 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.
Fast switching thyristors are supplied in stud design. The base of the thyristor is the Anode, the flexible power lead is the Cathode, the flexible wire exiting the base of the power lead is the auxiliary cathode, the flexible wire exiting the case is the control electrode (Gate). This thyristor can be an alternative product, replacement, analog, equivalent for other types fast switching thyristors 80A, 90A, 100 amp in a stud housing.
Air and water heat sinks are used to cool the thyristors. To provide reliable thermal and electrical contact with the heatsink a tightening torque Md must be observed during assembly. For better heat dissipation of thyristor during assembly, heat conducting paste is used.
