DESCRIPTION

The TURBOSWITCH is a very high performance

series of ultra-fast high voltage power diodes.

TURBOSWITCH family drastically cuts losses in

both the diode and the associated switching IGBT

and MOSFET in all freewheel mode operations

and is particulary suitable and efficient in motor

control freewheel applications and in booster diode

applications in power factor control circuitries.

Available either in SMB or F126 axial package,

these 600V devices are particularly intended for

use on 240V domestic mains.

The way of calculating the power losses is given

below :

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.
