DESCRIPTION
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 TO-220AC, isolated TO-220AC and
D2PAK, these 600V devices are particularly
intended for use on 240V domestic mains.

APPLICATION DATA
The TURBOSWITCH is especially designed to
provide the lowest overall power losses in any
“FREEWHEEL
Mode”
application
(Fig.A)
considering both the diode and the companion
transistor, thus optimizing the overall performance
in the end application.
The way of calculating the power losses is given
below:
