Operating junction temperature range is -65°C to 150°C. ## AEC-Q101 qualification and deployment context AEC-Q101 qualification means this part is certified for automotive-grade stress tests: temperature cycling, high-temperature reverse bias, and ESD robustness. It is suitable for 24V and 48V board-net transients in engine-control units, infotainment, and ADAS modules. The 342 V standoff rating protects 400 V nominal bus lines common in telecom rectifiers and industrial power supplies. At 1500 W surge capability, it handles lightning-induced transients per IEC 61000-4-5 without external series resistance. The DO-214AB (SMC) package has a 0.260-inch (6.60 mm) body length and 0.245-inch (6.22 mm) width, with a gull-wing lead form. The copper pad area under the cathode tab sets the junction-to-ambient thermal resistance; a 1 oz copper land pattern per Vishay application note is recommended for full 1.5 kW rating. Supplied on 13-inch tape and reel per EIA-481, compatible with standard pick-and-place equipment. The package is RoHS compliant and halogen-free per Vishay's green policy. The part is sourced through authorized and independent channels with full lot traceability.","metaTitle":"1.5SMC400AHM3_A/H TVS Zener 1.5kW 342V DO-214AB SMC","metaDescription":"Vishay 1.5SMC400AHM3_A/H TVS Zener diode, 1.5kW peak pulse power, 342V standoff, AEC-Q101 qualified.
