Its 21.7 V clamping maximum at the peak pulse current of 184 A (8/20 µs waveform) gives the downstream circuitry a defined voltage ceiling during a surge event. The 11.4 V minimum breakdown voltage ensures the diode starts conducting before the protected line exceeds safe levels. The 21.7 V clamping voltage at 184 A tells you the worst-case voltage the load sees during a pulse; a downstream regulator or IC must survive that peak. It is RoHS compliant and available for order.","metaTitle":"SM6T12A TRANSIL TVS Diode, 600 W, 10.2 V Standoff, DO-214AA","metaDescription":"STMicroelectronics SM6T12A 600 W unidirectional TVS diode, 10.2 V reverse standoff, 21.7 V clamp, DO-214AA SMB.
