A2 A2 K K A1 A1 TO-247 STTA3006CW SOT93 STTA3006CP 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 control freewheelapplicationsand 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.
