TURBOSWITCH™ ULTRA-FAST HIGH VOLTAGE DIODE

STMicroelectronics 

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.
