FEATURES AND BENEFITS
SPECIFIC TO THE FOLLOWING OPERATIONS:
SNUBBING OR CLAMPING, DEMAGHETIZATION
AND RECTIFICATION
ULTRA-FAST AND SOFT RECOVERY
VERY LOW OVERALL POWER LOSSES IN
BOTH THE DIODE AND THE COMPANION
TRANSISTOR
HIGH FREQUENCY OPERATION
HIGH REVERSE VOLTAGE CAPABILITY
SMC
DESCRIPTION
TURBOSWITCH 1200V drastically cuts losses in
all high voltage operations which require extremely
fast, soft and noise-free power diodes.
Due to their optimized switching performances
they aloso highly decrease power losses in any
associated switching IGBT or MOSFET in all
”freewheel mode” operations and is particulary
suitable and efficient in motor control circuitries, or
in primary of SMPS as snubber, clamping or
demagnetizingdiodes secondary of SMPS as high
voltage rectifier diodes. They are also suitable for
the secondary of SMPS as high voltage rectifier
diodes.

APPLICATION DATA
The 1200V TURBOSWITCH has been designed
to provide the lowest overall power losses in any all
high frequency or high pulsed current operations.
