Fast Switching Thyristors TFI (100A-320A) Stud Package
Fast Switching Thyristors (TFI) JY ENERGITM in stud design, also called “Fast Impulse Thyristors” (TFI) is a fast switching semiconductor device.
Fast switching 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 320A at frequency range is up to 10kHz in circuits with voltages to 1800V (depending on series). Power stud fast switching thyristors series TFI have the following types (current): 100 A, 120 A, 125 A, 150 A, 160 A, 200 A, 250 A, 300 A, 320 Ampere.
Fast switching thyristors are thyristors with additionally normalized reverse recovery charge Qrr.
These devices are adapted for switching current pulses with a high rate of rise at the front and high amplitude. 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 switching (pulse) 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 switching 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 600 to 1800 V and amperages from 100 to 320 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 switching thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.

Installation recommendations for power thyristors:
The reliability of heat transfer and electrical contact between the mating surfaces of the thyristor and the cooler over the entire temperature range is ensured by appropriate torque (clamping force).
Before assembly you should perform visual inspection (1) contact surfaces for mechanical damages and wipe (2), soaked with alcohol (toluene, gasoline, acetone). After inspection, fix the current contacts (leads), install a pin to fix the alignment of the structure.
To improve the parameters of heat transfer it is recommended to lubricate (3) a thin layer of silicone thermal conductive paste before the assembly, which is not a mandatory condition for installation.
Install the thyristor (3), the second part of the cooler, the fiberglass insulator and the thrust washer.
To thread the traverse (4) and evenly tighten the nuts. Make sure no misalignment and evenness of the contact surfaces. When the parts are sufficiently clamped but moveable, we recommend placing the cooler on a flat surface and checking the tolerance for parallelism of the overall adjacent plane of the surfaces (5).
Clamp each nut in turn (about a quarter turn) to the stop (6). The amount of deflection of the traverse determines whether the achieved clamping force corresponds to the required one. After installation, the fasteners (nuts and washers) must be additionally secured against corrosion.
