With a 12.8V reverse standoff voltage, it sits on a nominal 12V bus and stays transparent until a surge pushes the line above 14.3V, where breakdown begins. The clamping voltage holds at 21.2V maximum while shunting 70.8A of peak pulse current (10/1000µs waveform) — enough to absorb load-dump and inductive kickback events common in engine-bay and chassis electronics. The -65°C to 150°C junction temperature range covers cold-crank starts and under-hood heat soak without derating the 1500W pulse capability. ## DO-214AB SMC footprint and tape reel packaging Housed in the DO-214AB (SMC) package, the 1.5SMC15AHE3/9AT uses the standard surface-mount footprint for 1500W TVS diodes. The Tape & Reel (TR) packaging suits automated pick-and-place assembly for high-volume automotive board builds. ## Active lifecycle with automotive compliance traceability The AEC-Q101 and TransZorb® series designation gives procurement teams the compliance documentation needed for PPAP submissions and automotive customer audits.","metaTitle":"1.5SMC15AHE3/9AT Vishay TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC15AHE3/9AT Zener TVS diode, 1500W peak pulse, 12.8V standoff, AEC-Q101 automotive grade.
