DS6130-1 October 2013 (LN31069)
FEATURES
Low Reverse Recovery Charge High Switching Speed Low Forward Volt Drop Isolated AlSiC Base With AlN Substrates Dual Diodes Can Be Paralleled For 2400A Rating
APPLICATIONS
Chopper Diodes Boost and Buck Converters Free-wheel Circuits Snubber Circuit Resonant Converters Induction Heating Multi-level Switch Inverters
The DFM1200XXM45-TS000 is a dual 4500V, 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.
The module incorporates an electrically isolated base plate and low inductance construction enabling circuit designers to optimise circuit layouts and utilise grounded heat sinks for safety.

ABSOLUTE MAXIMUM RATINGS
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.
