HIGH FREQUENCY OPERATIONS
DESCRIPTION
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
DO-201AD
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.
