It is qualified to AEC-Q101, the automotive discrete semiconductor reliability standard, making it suitable for ECU and under-hood transient protection where PPAP documentation is required. The reverse standoff voltage is 36.8 V, and breakdown occurs between 40.9 V minimum. ## AEC-Q101 qualification and automotive fit AEC-Q101 qualification means the part has passed stress tests including temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive council's discrete semiconductor standard. This is the baseline for any Tier-1 ECU BOM that requires traceable reliability data. The 150°C maximum junction temperature aligns with under-hood ambient profiles where the TVS may see sustained heat soak. The -65°C low end covers cold-crank and arctic storage conditions without parametric shift. No power line protection is claimed — this is a unidirectional transient suppressor for signal or low-side DC rails, not for AC mains or hot-swap bus clamping. The DO-214AB (SMC) footprint is a standard JEDEC outline for 1.5 kW TVS diodes. The copper pad area under the cathode tab sets the thermal resistance — a larger pad lowers RthJA and improves surge derating at elevated ambient temperatures. The reel quantity is not specified here but is standard for the SMC package size. No official second-source or pin-compatible cross-reference is recorded in this listing.","metaTitle":"Vishay 1.5SMC43AHE3/57T TVS Diode, 1.5kW, DO-214AB","metaDescription":"Vishay 1.5SMC43AHE3/57T Zener TVS, AEC-Q101 qualified, 1500W peak pulse, 36.8V standoff, DO-214AB.
