Breakdown occurs at a minimum of 17.1 V, giving margin before the clamp activates. ## Automotive-grade transient suppression It is intended for load-dump, inductive kickback, and surge protection on power lines in engine control units, body controllers, and infotainment systems. The bidirectional configuration protects against both positive and negative transients with a single device, simplifying BOM count on bipolar or AC-coupled lines. The 1500 W rating at 10/1000 µs covers most automotive transient classes defined in ISO 7637-2 and ISO 16750-2. ## Sourcing and compliance The base product number is 1.5SMC18, indicating the 18 V breakdown family.","metaTitle":"Vishay 1.5SMC18CAHE3/9AT TVS, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC18CAHE3/9AT bidirectional Zener TVS, 1500W peak pulse, 15.3V standoff, AEC-Q101, DO-214AB.
