DESCRIPTION The TURBOSWITCH is a very high performance series of ultra-fast high voltage power diodes from 600V to 1200V. TURBOSWITCH family, drastically cuts losses in both the diode and the associated switching IGBT or MOSFET in all "freewheel mode" operations and is particularly suitable and efficient in motor ABSOLUTE RATINGS (limiting values, per diode) Symbol VRRM VRSM IF(RMS) IFRM IFSM Tj Tstg Parameter Repetitive peak reverse voltage Non repetitive peak reverse voltage RMS forward current Repetitive peak forward current Surge non repetitive forward current Storage temperature range tp = 5 s F = 5kHz square tp=10 ms sinusoidal Value 600 600 30 200 230 150 -65 to 150 Unit V V A A A C C control freewheel applications and in booster diode applications in power factor control circuitries. Packaged either in TO-247 or SOT93, these 600V devices are particularly intended for use on 240V domestic mains.

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. The way of calculating the power losses is given below:
TOTAL LOSSES due to the diode P = P1+ P2+ P3+ P4+ P5
Watts
CONDUCTION LOSSES in the diode
REVERSE LOSSES in the diode
SWITCHING LOSSES in the diode
SWITCHING LOSSES in the tansistor
