The 1500 W rating means this part absorbs a single surge event without failing — useful for automotive load-dump, inductive kickback, and telecom line transients where the energy is high but short-lived. ## AEC-Q101 grade for under-hood and chassis electronics Qualified to AEC-Q101, the automotive discrete semiconductor stress test standard. The -65°C to 150°C junction temperature range covers engine-bay ambient and cold-crank conditions without derating the surge capability. ## Active production — no end-of-life watch needed The Tape & Reel packaging aligns with high-volume pick-and-place lines.","metaTitle":"Vishay 1.5SMC18CAHM3_A/I TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC18CAHM3_A/I bidirectional Zener TVS, 1500W peak pulse power, 15.3V standoff, AEC-Q101 qualified.
