Due to their optimized switching performances they also highly decrease power losses in any associated switching IGBT or MOSFET in all “freewheel mode” operations. ABSOLUTE RATINGS (limiting values) Symbol VRRM VRSM IF(RMS) Parameter Repetitive peak reverse voltage Non repetitive peak reverse voltage RMS forward current TO-220AC / DPAK ISOWATT220AC / TO-220FPAC IFRM IFSM Tstg Tj Repetitive peak forward current Surge non repetitive forward current Storage temperature range Maximum operating junction temperature tp = 5 µs F = 5kHz square tp = 10ms sinusoidal They are particularly suitable in motor control circuitries, or in the primary of SMPS as snubber, clamping or demagnetizing diodes. They are also suitable for secondary of SMPS as high voltage rectifier diodes. Value 1200 1200 20 10 70 45 - 65 to + 150 150 Unit V V A A A A °C °C TURBOSWITCH is a trademark of STMicroelectronics.
