TURBOSWITCH is a trademark of STMicroelectronics

November 1999 - Ed: 5A

SPECIFIC TO THE FOLLOWING OPERATIONS:

SNUBBING OR CLAMPING, DEMAGNETIZATION

AND RECTIFICATION

ULTRA-FAST AND SOFT RECOVERY

VERY LOW OVERALL POWER LOSSES IN

BOTH THE DIODE AND THE COMPANION

TRANSISTOR

HIGH FREQUENCY OPERATION

HIGH REVERSE VOLTAGE CAPABILITY

FEATURES AND BENEFITS

TURBOSWITCH 1200V drastically cuts losses in

all high voltage operationswhich require extremely

fast, soft and noise-free power diodes.

Due to their optimized switching performances

they also highly decrease power losses in any

associated switching IGBT or MOSFET in all

freewheel mode operations.

They are particularly suitable in motor control

circuitries, or in primary of SMPS as snubber,

clamping or demagnetizing diodes. They are also

suitablefor the secondaryof SMPSas high voltage

rectifier diodes.
