The TURBOSWITCH is a very high performance
series of ultra-fast high voltagepowerdiodes from
600Vto1200V.
TURBOSWITCH family, drastically cuts losses in
boththe diodeand the associatedswitching IGBT
or MOSFET in all ”freewheel mode” operations

and is particularly suitable and efficient in motor
controlfreewheelapplicationsandin boosterdiode
applicationsin power factorcontrolcircuitries.
Packaged either in TO-220AC, ISOWATT220AC
or in DPAK, these 600V devices are particularly
intendedfor useon 240V domesticmains.

APPLICATIONDATA

STTA506D/F/B

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.
