The 18.8 V reverse standoff voltage defines the DC operating rail it protects — a 12 V or 15 V bus with margin. ## Automotive-grade clamping for 12 V / 15 V rails AEC-Q101 qualification means this part passed the automotive stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the JEDEC standard for discrete semiconductors. Breakdown occurs at 20.9 V minimum, so the device stays off below that threshold and only conducts during a transient event — no leakage on the nominal rail. The DO-214AB (SMC) surface-mount package handles the 1500 W pulse without exceeding the junction limit when the PCB copper area follows the recommended footprint.","metaTitle":"1.5SMC22AHE3_A/H TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"Vishay 1.5SMC22AHE3_A/H Zener TVS, 1500W peak pulse, 18.8V standoff, AEC-Q101 qualified.
