The DFM400PXM33-A000 is a series pair 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
make the device suitable for the latest drive designs
employing pwm and high frequency switching.
These 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.
