The DFM900NXM45-F000 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.
