It is a unidirectional device (one channel) designed to clamp fast overvoltage transients on a single rail. ## Automotive-grade qualification and temperature range This part is AEC-Q101 qualified, meaning it has passed the automotive-grade stress tests (temperature cycling, high-temperature reverse bias, ESD) required for under-hood and cabin electronics. The TransZorb® technology in this series provides a sharp breakdown characteristic and low clamping factor, which matters when the protected circuit has a tight voltage margin above the 459 V standoff. For existing BOM lines, the part is sourced through independent surplus and broker inventory. Quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement from Vishay is documented, so a board-level qualification of any substitute is required.","metaTitle":"1.5SMC540AHE3_A/I Vishay TVS, 1500W, DO-214AB, 459V","metaDescription":"Vishay 1.5SMC540AHE3_A/I Zener TVS, 1500W peak pulse, 459V standoff, DO-214AB.
