Thyristor Module

Thyristor Modules consist of 1 or 2 thyristors (SCR’s)in a combination of 4 types of circuits. The diodes can be arranged in Single, Series, Common Anode or Common Cathode configuration, depending on the requirement. The modules are constructed with glass passivated chips and the package is electrically isolated with a metal baseplate (usually copper) or sometimes a DCB Alumina base (Al2O3)

These modules have high efficiency, compact packaging, low thermal resistance, high stability at high temperatures & high di/dt and dv/dt capabilities.

The Thyristor Modules areused in online/offline inverters, battery chargers, power supplies, motor drives, single and three phase bridge circuits, industrial welders & heat/temperature control circuits.

  • The current range starts from 25A upto 600A, with voltages upto 2400V.
  • Devices are available in Module Packaging (M1, M3, M4, M5)
