The 1.5SMC20AHR7G: Automotive-grade qualification per AEC-Q101 certifies the part for -55°C to 150°C junction temperature — the full under-hood temperature band. The qualification includes high-temperature reverse bias (HTRB) and temperature cycling stress, so the TVS holds its breakdown voltage and leakage over the engine bay thermal profile. The copper pad area under the cathode tab sets the junction-to-ambient thermal resistance; a 1 oz copper pour of at least 645 mm² on the PCB keeps the die temperature below the 150°C limit during repetitive surges.
