The -65 °C cold start capability covers equipment that must function before the engine warms up. Surface-mount DO-214AB (SMC) packaging handles the board-level thermal cycling; the TransZorb construction gives the junction some immunity to moisture ingress compared to a plain Zener pellet. ## Automotive and telecom deployment context AEC-Q101 qualification means this part has passed the automotive board-level stress battery — temperature cycling, humidity, surge, and mechanical shock. For telecom 48 V rail protection, the same 6.45–10.5 V clamping window protects sensitive PHY and RS-485 interface ICs that run on 5 V rails.","metaTitle":"Vishay 1.5SMC6.8CAHM3/H Zener TVS Diode, 1500W","metaDescription":"Vishay 1.5SMC6.8CAHM3/H — Automotive AEC-Q101 Zener/TransZorb, DO-214AB SMC, 1500W peak pulse, 5.8V standoff.
