Stud Thyristors 10-50A Vishay Replacements
Power phase control thyristors, also known as Thyristor SCR (Silicon Controlled Rectifier), stud version 10-50A are general-purpose thyristors, regulating and converting DC and AC currents up to 50A in circuits with voltages to 1200V (depends on the thyristor type).
Stud Thyristors ASTS JY 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.
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 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 phase control stud thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
