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 the primary of SMPS as snubber,
clamping or demagnetizing diodes. They are also
suitable for secondary of SMPS as high voltage
rectifier diodes.
