The DFM1200NXM33-A000 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.

ABSOLUTE MAXIMUM RATINGS - PER ARM
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.
