DESCRIPTION

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

applicationsin power factor controlcircuitries.
Packaged either in TO-220AC, insulated
TO-220AC or in D

PAK, these 600V devices are
particularly intended for use on 240V domestic
mains.
