Stud Thyristors Vishay Replacement

Power phase control thyristors, also known as Thyristor SCR (Silicon Controlled Rectifier), stud version are general-purpose thyristors, regulating and converting DC and AC currents up to 330A in circuits with voltages to 2000V (depends on the thyristor type).

Stud Thyristors ASTS AS ENERGITM are a replacement, analog, alternative for stud version of electrical triggered thyristors Vishay Semiconductors.

"Air-cooled heatsinks O series for stud devices", for thyristor cooling are also available to order.

Part numbering guide for phase control thyristors

icon AS ENERGITM Semiconductors Manufacturing Reference

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.

Thyristors AS 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.

Installation recommendations for power stud mount thyristors:

Assembling stud thyristor with a heatsink

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.

Before assembly you should perform visual inspection (1) contact surfaces for mechanical damages and wipe (2), soaked with alcohol (toluene, gasoline, acetone).

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.

After installation, the fasteners (nuts and washers) must be additionally secured against corrosion.


Tips and recommendations for power thyristors:

The power thyristors should not be operated for long periods of time at their limit load for all parameters. In this case, the safety factor is determined by the required degree of reliability of the device.

Replace a failed power thyristor with a thyristor that matches the parameters of the one being replaced.

Supercooling must be provided when operating in an environment with an elevated ambient temperature.

Periodic cleaning of power thyristors and coolers to remove dust and contaminants is recommended to ensure proper heat dissipation.

Inductive current dividers (often twisted toroidal wire) should be used to equalize currents between power thyristors connected in parallel. The most popular connection methods are closed circuit, common coil circuit, or power thyristor. The efficiency of current dividers in this case is determined by the cross section of the magnetic wire.

Prevention of voltage unbalance when power thyristors are connected in series is achieved by using shunt resistors connected in parallel with each thyristor. Voltage equalization in transient conditions is provided by connecting capacitors in parallel to each thyristor.

Device under voltage

It is strictly forbidden to touch power thyristors under high voltage during operation.

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.
