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 SiC devices.
Allows downsizing of mosfet and heatsinks

■ Internal ceramic insulated devices with equal

thermal conditions for both 300 V diodes

■ Insulation (2500 V

same heatsink as mosfet and flexible
heatsinking on common or separate heatsink

■ Static and dynamic equilibrium of internal

diodes are warranted by design

■ Package Capacitance: C = 7 pF

Description

The TURBOSWITCH “H” is an ultra high
performance diode composed of two 300 V dice
in series. TURBOSWITCH “H” family drastically
cuts losses in the associated MOSFET when run
at high dI
