The AGA 2000-45-H-02 by AS ENERGITM serves as a direct drop-in replacement for the Hitachi Energy 5SGA 20H4502 gate turn-off thyristor. This alternative device matches the original specifications, offering equivalent performance and reliability for demanding industrial applications.
Key ratings include an average forward on-state current (ITAV) of 710 A and a repetitive peak off-state voltage (VDRM) of 4500 V. To ensure optimal thermal management, compatible air and water heatsinks are available upon request.
Features: Asymmetric design ensures low switching losses, rapid turn-on/turn-off times, and enhanced di/dt capability. Proper polarity (anode and cathode) is clearly indicated by the standardized symbol on the robust disc housing.
AS ENERGITM thyristors are engineered for severe thermal and electric cycling, making them suitable for heavy-duty switching networks. We provide a 2-year warranty from the date of purchase, accompanied by technical passports and certificates of conformity upon delivery.
Specifications and parameters, datasheet PDF, dimensions, drawings are listed below.
The final price for standard recovery diodes in stud design depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.

according to your requests and technical task.
Heat sinks for power disc thyristors:
Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc design.
Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.
Air and water heat sinks for thyristor cooling are also available to order.
See for more information about heatsinks: "Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series".
