Features
• Ultrafast Recovery Time
• Low Forward Voltage Drop
• Low Leakage Current
• 175°C Operating Junction Temperature
Description/ Applications
International Rectifier's 300V series are the state of the art Ultrafast recovery rectifiers designed with optimized
performance of forward voltage drop and Ultrafast recovery time.
The planar structure and the platinum doped life time control guarantee the best overall performance, ruggedness
and reliability characteristics.
These devices are intended for use in the output rectification stage of SMPS, UPS, DC-DC converters as well as
freewheeling diodes in low voltage inverters and chopper motor drives.
Their extremely optimized stored charge and low recovery current minimize the switching losses and reduce over
dissipation in the switching element and snubbers.
