AEC-Q101 qualification and a -65°C to 150°C junction temperature range put this part in the under-hood / engine-bay deployment class — the thermal margin covers the 105°C ambient a summer-grade ECU sees, plus the self-heating from repetitive pulses. DO-214AB (SMC) surface-mount package, also designated as SMCJ by the supplier device code. No official successor or pin-compatible cross-reference is documented — the 1.5SMC18AHE3/57T is the current production order code for this voltage and package variant.","metaTitle":"Vishay 1.5SMC18AHE3/57T TVS Diode, 1.5kW, DO-214AB","metaDescription":"Vishay 1.5SMC18AHE3/57T Zener TVS diode, 1500W peak pulse power, 15.3V standoff, AEC-Q101 automotive grade.
