Disc type thyristors (SCR) and disc diodes are press-pack power semiconductor devices for high-power, high-current industrial applications. The flat disc structure is clamped between double-sided heat sinks, providing superior thermal performance, uniform current distribution, and high mechanical reliability.

Our main range covers phase control thyristors (KP series) and fast thyristors (KK series), 200A–5000A, 200V–8500V. Additional types available on request.

Key Features & Applications

Phase control thyristors (KP series) and fast thyristors (KK series) support series and parallel configurations for demanding power systems. Suitable for high-power rectifiers, medium and high voltage soft starters, HVDC transmission, large motor drives, industrial furnaces, and heavy industry applications including mining and metallurgy.
