The DFM600FXM18-A000 is a dual 1800V, 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.
