FEATURES AND BENEFITS
The TURBOSWITCH is a very high performance
series of ultra-fast high voltage power diodes from
600V to 1200V.
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 applicationsand in booster diode
applications in power factor control circuitries.
Packaged either in SOD93 or in DOP3I, these
600V devices are particularly intended for use on
240V domestic mains.

application
(Fig.A)
considering both the diode and the companion
transistor, thus optimizing the overall performance
in the end application.
