Fast Thyristors, Stud Type, Vishay Replacement
Fast Thyristorin stud design are general-purpose thyristors, regulating and converting DC and AC currents up to 330A in circuits with voltages to 1200V (depends on the thyristor type).
Fast Thyristors (Stud Type) ASTS JY ENERGITM are a replacement, analog, alternative for stud version of fast thyristors Vishay Semiconductors. “Air-cooled heatsinks O series for stud devices”, for thyristor cooling are also available to order.
Features: designed for high power industrial and power transmission applications; optimized for low on-state voltage drop; matched Qrr and VT values available for series and / or parallel connections. 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 (this is a recommendation and is not a prerequisite for installation).
Features: 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 thyristors are notable for their ability to be used on moving parts. Fast thyristors are devices with reduced tq, trr, Qrr values and with a higher value (diT/dt)crit (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.
Thyristors JY ENERGITM 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 100 to 9000 V and amperages from 100 to 15000 A, high resistance to thermal and electric cycling, natural or forced air cooling.
Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide technical passport and certificate of conformity.
The final price of fast thyristors in stud design 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.
