IXYS UK Westcode, a subsidiary of IXYS, has expanded its portfolio of 83mm die phase control thyristors. Rated at 2.2kV, the devices use an integrated die construction and improved package design for better electromechanical and thermal performances, stated the company.

The thyristor has an average current rating (case temperature 55C) of 4340A, with a junction to heat sink thermal resistance of 0.008K/W. It is constructed using an all diffused silicon wafer slice fused to a metal header and encapsulated in a fully hermetic package. This construction enhances the performance and provides excellent transient thermal and surge current ratings, IXYS added.

The device is available in two industry standard capsule heights and two different voltage grades. Designations are: one inch thick package N4340TJ220 (2.2kV), N4340TJ180 (1.8kV); one and a half inch thick package N4340TE220 (2.2kV), N4340TE180 (1.8kV). Additional products with voltage ratings up to 6.5kV will be launched through 2013.

Typical applications for these devices include industrial drives, wind power converters, soft starters, excitation, utilities and controlled rectifiers.
