Pulse Thyristors - Capsule Types WESTCODE Home
Westcode has long since been at the forefront of solid state pulsed power technology, offering custom solutions to complex pulsed power problems. Pulse thyristors are, in essence, optimised Gate Turn-off Thyristors and as such we are able to offer a flexible range of parts depending on customer needs.
Devices with voltage ratings to 2.5kV, pulsed currents to 150kA peak and di/dt capabilities to over 30kA/microsecond are available. A selection of preferred parts is shown here, for other parts and technical support please contact the factory
