DESCRIPTION
TURBOSWITCH 1200V drastically cuts losses in
all high voltage operationswhich 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 the primary of SMPS as snubber,
clamping or demagnetizing diodes. They are also
suitable for secondary of SMPS as high voltage
rectifier diodes.

APPLICATION DATA
The 1200V TURBOSWITCH series has been
designed to provide the lowest overall power
losses in all high frequency or high pulsed current
operations. In such applications (Fig A to D),the
way of calculating the power losses is given below:
