This clamping level is the voltage the protected circuitry sees during a surge; a 15.9V clamp is safe for 12V rails but too high for 3.3V logic without additional series resistance. ## Temperature range and application environments The device is rated for General Purpose applications – no power-line protection or AEC-Q automotive qualification is listed, so it is not formally qualified for automotive use despite the wide temp range.","metaTitle":"SMAJ8.5CE3/TR13 Zener TVS, 500W, DO-214AC – Microchip","metaDescription":"Active-production Zener TVS diode, 8.5V reverse standoff, 15.9V clamping at 31.4A.
