1200Â V dual phase-control thyristor module in the compact 94Â mm class. Rated 142Â A average per arm at
TC=85 °C with very high surge capability, this block is common in soft-starts, rectifiers, and UPS front-ends.
The isolated baseplate and robust gate characteristics simplify thermal design and service.
