No power line protection (the device is unidirectional, so it clamps only positive transients above the breakdown voltage; negative surges forward-bias the Zener junction). Mounting is surface-mount on a standard SMC footprint — the 0.30 mm lead pitch and JEDEC outline match automated pick-and-place. ## Active production and sourcing posture No official second-source or pin-compatible alternative is listed in this series for the same AEC-Q101 qualification.","metaTitle":"1.5SMC12AHE3/9AT Vishay TVS, AEC-Q101, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC12AHE3/9AT Zener TVS diode, AEC-Q101 qualified, 1500W peak pulse, 10.2V standoff, DO-214AB.
