DFM300MXS18-A000 DFM300MXS18-A000 Fast Recovery Diode Module Preliminary Information DS5458-1.1 May 2001 FEATURES s Low Reverse Recovery Charge s High Switching Speed s Low Forward Voltage Drop s Isolated Base KEY PARAMETERS VRRM VF (typ) (max) IF (max) IFM 1800V 2.0V 300A 600A APPLICATIONS s Brake Chopper Diode s Boost and Buck Converters s Free-wheel Circuits s Motor Drives s Resonant Converters s Induction Heating s Multi-level Switch Inverters 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. 1 2 3 2 1 3 Fig. 1 Circuit diagram ORDERING INFORMATION Order As: DFM300MXS18-A000 Note: When ordering, please use the complete part number.
