IXYS Corporation (NASDAQ:IXYS) an international power and IC semiconductor company, today announced that its wholly owned UK subsidiary, IXYS UK Westcode Ltd., launched a 500A, 2.5KV GTO thyristor in a new smaller package.
The new GTO (gate turn-off) thyristor rated at 500A and 2.5kV is based on IXYS UK’s established S500KC device. The die design has the same active area and performance, but with an improved termination design which allows the device to be encapsulated in a smaller 25mm pole face package. As with all IXYS UK’s small area devices the die uses IXYS’ proven and reliable long finger pattern emitter technology, which offers unrivalled thermal cycling and mechanical durability. The device uses an all diffused process and is part of IXYS UK’s extensive symmetrical structured portfolio, using life-time control techniques to give optimum switching and on-state losses. The die is encapsulated in a fully hermetic package.
“This new introduction demonstrates IXYS UK’s continued commitment to manufacture these small die GTO thyristors when most of the competition has withdrawn such products. GTOs are still the highest power density devices in their class for very high power applications. This particular device was a perceived gap in our portfolio and ensures that IXYS UK is able to support our customers in replacing now obsoleted competitor parts as a one-stop suppler for all their GTO thyristor needs,” commented Frank Wakeman, IXYS UK’s Marketing & Technical Support Manager.
The device is available in two different voltage grades. Designations are: S0500YC20Y (Vdrm 2000 Volts and Vrrm 100 Volts) and S0500YC20Y (Vdrm 2500 Volts and Vrrm 100 Volts).
Typical applications include traction auxiliaries, plus main drives for light rail, trams and trolleybuses.
