The DFM300MXS18-A000 is a dual 1800 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.
The module incorporates an electrically isolated base
plate. Low inductance construction enables circuit
designers to optimise circuit layouts and utilise grounded
heat sinks for safety.
