The DFM600BXS12-A000 is a single 1200V, 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 incorporates electrically isolated base plates and low inductance construction enabling circuit designers to optimise circuit layouts and utilise grounded heat sink for safety.
