Fast Power Thyristors 80A – 250A, Stud Package
Fast Thyristor (TF) JY ENERGITM in stud design is a fast switching semiconductor device. Fast 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 250A at frequency range is up to 10kHz in circuits with voltages to 1400V (depending on series).
Power stud fast thyristors series TF have the following types (current): 80 A, 100 A, 125 A, 160 A, 200 A, 250 Ampere.
Fast 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 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 polarity of the thyristor is determined by the icon on the case. On this page are schematic diagrams and circuits of stud fast thyristors with Anode, Cathode, and control electrode (Gate). The technical specifications, part numbering guide, polarity, dimensions and recommended coolers for stud fast thyristors are listed below. Air and water heat sinks are used to cool the stud 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. The fast thyristors have a sealed ceramic housing isolating the functional part and the semiconductor element from mechanical impacts and environment.
Fast stud thyristors from AS Energi Global LLC have the following features: low static and dynamic losses, high values of VDRM/VRRM, extensive experience of using the devices in various industries, range of voltages from 300 to 1400 V and amperages from 80 to 250 A, high resistance to thermal and electric cycling, natural or forced air cooling. Our company provides a quality guarantee for stud thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide quality declaration and certificate of conformity.
The final price of fast thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
