Santa Clara, Calif.IXYS Corp.'s UK-based wholly owned subsidiary, Westcode Semiconductors Ltd. (Westcode), has launched a 1300-A, 5.5-kV extra-fast recovery diode.
The device is available in three voltage grades, identified by part numbers F1300NC45P 4.5-kV, F1300NC50P5-kV and F1300NC55P 5.5-kV. All are encapsulated in a fully hermetic, ceramic-walled package with 47-mm diameter copper pole faces.
The devices offer low-loss characteristics, giving designers the ability to design more energy-efficient rectifiers in medium-voltage applications.
"The new design uses specialized processing techniques to give a vertical PIN structure, optimizing the forward voltage drop, up to 200-V at forward current 1300-A, against the 5.5-kV blocking voltage," said Frank Wakeman, marketing and evaluation manager of Westcode, in a statement. "Advanced life-time control techniques results in an extra fast diode with a reverse recovery time of 15 microseconds and di/dt capability greater than 1000 amps per micro second, overall result in a 5.5-kV device with low on-state losses but extra fast switching, without compromising on current rating or maximum operating temperature."
The F1300NC45P, F1300NC50P and F1300NC55P can be used as anti-parallel or clamp diodes in conjunction with IGBTs, IGCTs or other fast switching devices in traction, medium voltage drives. The high di/dt and low forward loss also make the devices operate as fast rectifiers in applications such as pulsed power or power conversion.
