June 2024 – IXYS UK Westcode Gate Turn-off Thyristors

Learn more about IXYS UK Westcode’s Gate Turn-off Thyristors and how they meet the toughest demands 

IXYS UK Westcode Gate Turn-off thyristors

IXYS UK Westcode offers a broad range of high specification devices with voltage ratings to 6kV (3.6kV DC link) and controllable current ratings of up to 4kA. IXYS UK’s GTO thyristors meet the toughest demands in applications such as traction propulsion and auxiliaries, AC industrial drives and active Var controllers. IXYS UK offers both symmetrical devices for applications with a reverse blocking requirement and asymmetric blocking devices for applications where no reverse blocking requirement exists.

The latest addition to IXYS UK’s range is the 4500V, 4000A G4000EF450 asymmetric GTO thyristor, available in a hermetically sealed capsule with an 85mm electrode diameter. New G3000HF600 in development.

Gate turn-off thyristors are ideal for very high-power converters and IXYS UK offers a range of complimentary products alongside its GTO range, which includes anti-parallel diodes, snubber diodes, snubber capacitors and clamps.
