FEATURES AND BENEFITS
SPECIFIC TO THE FOLLOWING OPERATIONS:
SNUBBING OR CLAMPING, DEMAGNETIZATION
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

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 also highly decrease power losses in any
associated switching IGBT or MOSFET in all
freewheel mode operations.
ABSOLUTE RATINGS (limiting values)
They are particularly suitable in motor control
circuitries, or in primary of SMPS as snubber,
clamping or demagnetizing diodes. They are also
suitable for the secondary of SMPS as high voltage
rectifier diodes.

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