Operating temperature spans -65°C to 150°C junction, covering the full industrial range and extending into under-hood automotive ambient conditions where the device must clamp reliably at high soak temperatures. ## Package and board integration Housed in the DO-214AB (SMC) surface-mount package, the 1.5SMC12A-M3/9AT uses the standard JEDEC footprint with a cathode band for polarity identification. The supplier device package reference DO-214AB (SMCJ) confirms the same mechanical outline, simplifying PCB layout across multiple Vishay TVS order codes. The base product number 1.5SMC12 allows cross-referencing to other package or reel options within the same voltage rating.","metaTitle":"1.5SMC12A-M3/9AT Vishay TVS, 1500W, 10.2V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC12A-M3/9AT Zener TVS diode, 1500W peak pulse power, 10.2V reverse standoff, unidirectional, DO-214AB (SMC).
