Stud thyristor VS-80RIA40

for control

Stud thyristor ASTS80RIA40AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for stud thyristors VS-80RIA40 Vishay Semiconductors. Average forward on-state current ITAV – 80 ampere, repetitive peak forward and reverse blocking voltage VDRM/VRRM – 400V. Stud thyristor are designed to convert and control DC and AC currents. "Air-cooled heatsinks O series for stud devices" for thyristor cooling are also available to order. 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. Specifications and parameters, datasheet PDF, dimensions, drawings are listed below. Our company provides a quality guarantee for thyristors of 2 years from the date of purchase.
