The junction temperature range spans -65 °C to 150 °C, covering the full automotive thermal profile from cold crank to under-hood soak. ## Package, footprint, and supply format Housed in a DO-214AB (SMC) surface-mount package, also designated as supplier device package SMCJ, with a standard JEDEC footprint for automated assembly. Mounting is surface mount only; the SMC package requires a copper land pattern per Vishay's application note for adequate thermal transfer during the 10/1000 µs pulse.","metaTitle":"Vishay 1.5SMC18CAHE3/57T TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC18CAHE3/57T bidirectional TVS, 1500W peak pulse, 15.3V standoff, AEC-Q101 qualified.
