TURBOSWITCH™ ULTRA-FAST HIGH VOLTAGE DIODE

STMicroelectronics 

APPLICATION DATA

The TURBOSWITCHTM is especially designed to

provide the lowest overall power losses in any

"Freewhell Mode" application (see fig. A)

considering both diode and companion transistor,

thus optimizing the overall performance in the end

application.

The way of calculating the power losses is given

below :
