DESCRIPTION
TURBOSWITCH 1200V drastically cuts losses in
allhighvoltageoperationswhich requireextremely
fast,soft andnoise-freepower diodes.Due to their
optimizedswitchingperformancesthey also highly
decrease power losses in any associated
switchingIGBT or MOSFET in all freewheelmode
ABSOLUTE RATINGS
(limitingvalues, perdiode)
operations.
They are particularly suitable in Motor Control
circuitries, or in the primaryof SMPS assnubber,
clampingor demagnetizingdiodes. They are also
suitable for secondary of SMPS as high voltage
rectifierdiodes.
