IXYS Corporation announced that its wholly owned UK subsidiary, IXYS UK Westcode Ltd., launched a new addition to its 83mm die phase control thyristors product group.
The thyristors, rated at 2200 volt, are the latest introduction to this new product group that uses an integrated die construction and improved package design for better electromechanical and thermal performances. The 2.2kV thyristor has an average current rating (Case temperature 55C) of 4340 amperes, with a junction to heat sink thermal resistance of 0.008 kelvins per watt. The new thyristor is constructed using an all diffused silicon slice fused to a metal disc and the die is encapsulated in a fully hermetic package. This construction enhances the performance and provides excellent transient thermal and surge current ratings.
The device is available in two industry standard capsule heights and two different voltage grades. Designations are: one inch thick package N4340TJ220 (2200 Volts), N4340TJ180 (1800 Volts); one and a half inch thick package N4340TE220 (2200 Volts), N4340TE180 (1800 Volts). Additional products with voltage ratings up to 6500 volts will be launched through 2013.
