The DKFT4000A / 19-25 Fast Turn-Off Thyristor is a high-power disc-type semiconductor device designed for demanding industrial switching and power control applications. It features an interdigitated amplifying gate, fast switching capability, high di/dt performance, and low switching loss for high-current power systems. With an average on-state current of 4000A and a repetitive peak off-state/reverse voltage range of 1900V to 3000V, this thyristor is suitable for converters, chopper circuits, and induction heating equipment. Its double-side cooled clamping structure provides reliable thermal performance in heavy-duty assemblies.
