Thyristor-Diode Modules consist of 1 diode and 1 thyristor (SCR) in a combination of 3 types of circuits. The diodes can be arranged in 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-Diode Modules areused in online/offline inverters, battery chargers, power supplies, motor drives, single and three phase bridge circuits, industrial welders & heat/temperature control circuits.
