October 2017 - IXYS UK Westcode Introduces a new 2.2kV Distributed Gate Thyristor

Published on: 06/10/2017

This week IXYS UK Westcode have announced a new pressure contact distributed gate thyristor with increased power density

IXYS UK Westcode 2.2kV Distributed Gate Thyristor

IXYS UK Westcode’s new fast thyristor with turn-off time of as little as 25μs and current rating 1605A, is symmetrical blocking with Vdrm/Vrrm equal to 2200V and therefore suitable for both voltage and current fed applications. 

This new fast thyristor has been introduced to compliment the asymmetric blocking R1700MC device and is based on the same die size, gate geometry and silicon design, however with the option of fully symmetrical blocking voltage up to the maximum available voltage of 2200V.

The 56mm diameter silicon die are bonded to a metal disc to ensure the best steady state and thermal transient performance. The die is encapsulated in fully hermetic 50mm electrode contact diameter ceramic packages, with an industry standard overall diameter of 74mm. Provided the correct thermal conditions are observed, with a repetitive di/dt rating of 1000A/μs the device can be used in applications with repetitive frequency up to 10kHz. 

The full symmetrical blocking device is available in five different switching classes at two standard voltage grades, part number designations are as follows: 2000 volt parts are R1605MC20E with tq 25μs, R1605MC20F with tq 30μs, R1605MC20G with tq 35μs, R1605MC20H with tq 40μs and R1605MC20J with tq 50μs; 2200 volts are R1605MC22E with tq 25μs, R1605MC22F with tq 30μs, R1605MC22G with tq 35μs, R1605MC22H with tq 40μs and R1605MC22J with tq 50μs.

Typical applications for this device include: induction power supplies for melting, billet heating and surface treatments; as well as resonant power supplies and pulse switches for applications including high power magnets and lasers.
