Fast Recovery Diode Module Prelimianry Information
FEATURES

s Low Reverse Recovery Charge s High Switching Speed s Low Forward Voltage Drop s Isolated Base s Dual Diodes Can Be Paralleled for 800A Rating s MMC Baseplate With AlN Substrates

APPLICATIONS

s Brake Chopper Diode s Boost and Buck Converters s Free-wheel Circuits s Motor Drives s Resonant Converters s Induction Heating s Multi-level Switch Inverters The is a dual 3300 volt, fast recovery diode (FRD) module. Designed for low power loss, the module is suitable for a variety of high voltage applications in motor drives and power conversion. Fast switching times and low reverse recovery losses allow high frequency operation making the device suitable for the latest drive designs employing pwm and high frequency switching. These modules incorporate electrically isolated base plates and low inductance construction enabling circuit designers to optimise circuit layouts and utilise grounded heat sinks for safety.

Stresses above those listed under 'Absolute Maximum Ratings' may cause permanent damage to the device. In extreme conditions, as with all semiconductors, this may include potentially hazardous rupture of the package. Appropriate safety precautions should always be followed. Exposure to Absolute Maximum Ratings may affect device reliability.
