For existing BOM lines, this part is sourced through independent distribution channels. ## Zener TVS — 1500 W peak pulse, 376 V standoff The minimum breakdown voltage is 418 V, ensuring the device begins conducting before the protected circuit's voltage rating is exceeded. ## DO-214AB (SMC) — surface-mount board fit Housed in a DO-214AB (SMC) package, this TVS is designed for reflow soldering onto a standard surface-mount PCB footprint. The single unidirectional channel means the cathode is tied to the protected rail; the anode connects to ground. It is not intended for AC power line protection.","metaTitle":"1.5SMC440A-E3/9AT Vishay Zener TVS, 1500W, 376V Standoff","metaDescription":"Vishay 1.5SMC440A-E3/9AT Zener TVS diode, 1500W peak pulse, 376V standoff, DO-214AB.
