Santa Clara, Calif.Westcode Semiconductors Ltd., IXYS Corp.'s wholly owned subsidiary based in the United Kingdom, has launched a 8000-A, 2800-V large-area fast thyristor.
The thyristor has an average current rating of 4001 amperes for a sink temperature of 55°C and is encapsulated in two types of fully hermetic press pack outlines with pole face electrodes 100-mm (4-inch) in diameter.
Options include industry-standard 36mm (1 3/4 inch) and 26mm (1 inch) thick packages. The part designations are R3968FC28x for the 2.8-kV, 36-mm (1 3/4 inch) thick package and R3968FD28x for the 2.8-kV, 26-mm (1 inch) device. 2kV and 2.4kV versions are also available as standard.
The thyristor includes an advanced vertical structure and a highly distributed gate design to deliver high switching characteristics without compromising the forward conduction losses. All device types can be supplied to one of four turn-off time limits: 60, 65, 70 and 100 microsecondsidentified by the letters K, L, M and N, replacing the x in the part number. Where required, devices can be selected for their reverse recovery characteristics or supplied in explosion-rated packages.
