For existing BOM lines that require this exact part number, supply is managed through independent distribution channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement from Vishay is documented. Any replacement candidate must match the DO-214AB (SMC) footprint and the unidirectional clamping characteristic to avoid a board spin. The SMC footprint is larger than the SMA/SMB siblings, providing a lower thermal resistance path for the 1500 W pulse — the copper pad area under the cathode tab directly sets the junction-to-ambient thermal impedance during the transient event. No power line protection is claimed, meaning this TVS is intended for signal or low-power rail clamping rather than AC mains or high-current DC bus suppression. The single unidirectional channel suits DC rails where polarity is fixed.","metaTitle":"1.5SMC400AHE3_A/H Vishay TVS, 1500W, 342V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC400AHE3_A/H Zener TVS diode, 1500W peak pulse, 342V reverse standoff, AEC-Q101 qualified.
