The 16.7V clamping voltage is the maximum the protected IC sees during the event; if the downstream part has a 14V abs-max rating, this TVS will not protect it. The breakdown voltage tolerance window (11.4V min to 16.7V clamp) is tight enough for 12V logic and sensor supplies but not for 5V or 3.3V rails; those need a lower standoff part. ## Package and board integration Through-hole axial package in DO-201AA (DO-27) outline — the leads are 0.96 mm diameter and the body is 5.3 mm diameter. It mounts in a 1.1 mm drilled hole and the leads are bent to the board or soldered into turret terminals. The axial form factor is common for point-to-point wiring and high-reliability through-hole assemblies where surface-mount reflow is not available.","metaTitle":"Vishay 1.5KE12A-E3/73 TransZorb TVS, 1.5kW, 10.2V Standoff","metaDescription":"Vishay 1.5KE12A-E3/73 TransZorb Zener TVS diode, 1500W peak pulse power, 10.2V reverse standoff, 16.7V clamp.
