The -55°C to 150°C junction temperature range covers underhood and engine-bay thermal profiles with margin; the 150°C TJ max is the absolute limit, not a continuous operating recommendation. ## Sourcing and compliance posture The 1.5SMC18AH is listed for Telecom applications but the AEC-Q101 grade extends its fit to automotive ECUs, battery management, and ADAS power rails. No power line protection (the TVS clamps transients, not continuous overvoltage). Standard compliance documentation (RoHS, REACH) is provided by the manufacturer.","metaTitle":"1.5SMC18AH TVS Diode, 1.5kW, AEC-Q101, DO-214AB","metaDescription":"1.5SMC18AH Zener TVS, 1500W peak pulse, 15.3V standoff, AEC-Q101 qualified.
