For a production line that already carries this TVS, the immediate decision is whether the remaining build quantity can be covered from available surplus inventory before a board spin to a replacement is required. ## Protection window — 256V standoff, 414V clamp at 3.6A The reverse standoff voltage is 256V — the rail it protects should sit below that level so the diode stays non-conducting during normal operation. Breakdown occurs at a minimum of 285V, and the clamping voltage is held to 414V maximum at the rated peak pulse current of 3.6A. ## AEC-Q101 automotive grade — the reliability gate The 1.5SMC300AHE3_A/I belongs to the Automotive, AEC-Q101 qualified 1.5SMC series, branded TransZorb®. AEC-Q101 certification means the part has passed the stress tests (temperature cycling, high-temperature reverse bias, humidity) required for automotive electronics — it is rated for under-hood and chassis-domain deployment where reliability screening is non-negotiable. ## DO-214AB SMC footprint — board-fit check The SMC footprint is larger than the smaller SMA/SMB siblings and handles the 1500W pulse without exceeding the package thermal limit — verify the copper pad area on your PCB matches the recommended land pattern for this body size. Packaged in Tape & Reel (TR) for automated pick-and-place assembly.","metaTitle":"1.5SMC300AHE3_A/I Vishay TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC300AHE3_A/I automotive TVS, 1500W peak pulse, 256V standoff, AEC-Q101.
