FEATURES AND BENEFITS
Especially suited as boost diode in continuous
■
mode power factor correctors and hard
switching conditions.
Designed for high di/dt operation. Hyperfast
■
recovery current to compete with GaAs devices.
Allows downsizing of mosfet and heatsinks.
■
Internal ceramic insulated devices with equal
thermal conditions for both 300V diodes.
■ Insulation (2500V RMS) allows placement on
same heatsink as mosfet and flexible
heatsinking on common or separate heatsink.
■
Matched diodes for typical PFC application
without need for voltage balance network.
