The 0.240\" x 0.260\" body with gull-wing leads demands a solder pad pattern that matches the manufacturer-recommended land — the cathode band orientation must be verified against the PCB silkscreen before reflow. ## Clamping performance — sizing for 400V DC bus protection Unidirectional Zener TVS with a 459V reverse standoff voltage and 513V minimum breakdown. In a 12V or 24V automotive system, the 459V standoff is far above the normal rail, so this part is sized for high-voltage transient protection (e.g., load-dump on a 48V mild-hybrid bus or alternator field decay on a 24V truck system). ## Automotive qualification and sourcing posture Part of the Automotive 1.5SMC series with AEC-Q101 qualification — the stress tests (HTRB, H3TRB, temperature cycling, ESD) are run per the automotive discrete semiconductor standard, making it suitable for under-hood and powertrain applications where reliability data is required for PPAP submission.","metaTitle":"Vishay 1.5SMC540AHE3_ALL TVS, 1500W, 459V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC540AHE3_ALL unidirectional Zener TVS, 1500W peak pulse, 459V reverse standoff, 740V clamp.
