HIGH FREQUENCY OPERATIONS
FEATURES AND BENEFITS
The TURBOSWITCH is a very high performance
series of ultra-fast high voltage power diodes.
TURBOSWITCH family, drastically cuts losses in
both the diode and the associated switching IGBT
or MOSFET in all freewheel mode operations and
is particularly suitable and efficient in motor control
freewheel applications and in booster diode
applications in power factor control circuitries.
Packaged in DO-201AD this 600V device is
particularly intended for use on 240V domestic
mains.
