The minimum breakdown of 71.3V sits above the 64.1V standoff, meaning the diode stays off and leaks minimally under normal operating conditions before snapping into conduction at the transient threshold. ## AEC-Q101 qualification — why it matters for automotive and telecom picks AEC-Q101 is the automotive stress-grade qualification for discrete semiconductors — it certifies the part passed temperature cycling, humidity bias, and surge lifetime testing to a level that a generic industrial TVS does not. Listed for both Automotive and Telecom applications — the junction temperature limit of 150°C gives headroom for under-hood ambient and outdoor telecom cabinet deployments where thermal cycling is the dominant wear mechanism. ## DO-214AB SMC surface mount — board integration checklist The DO-214AB (SMC) package is the common DO-214AB half-width variant — the cathode band identifies polarity, and the anode tab lands directly to the PCB plane for thermal relief on high-current transients. Tape-and-reel packaging supports standard SMT pick-and-place assembly — confirm the reel quantity and whether the production burn-in and test temperature profile is compatible with your reflow oven thermal budget. Available through independent distribution channels; current pricing and lead times are confirmed against your BOM quantity at RFQ. The base product number 1.5SMC75 anchors the series — any parametric search on the 75V TVS family within the 1.5SMC line is a starting point for second-source alternatives if your BOM hedge requires it.","metaTitle":"Vishay 1.5SMC75AHM3/H, 1500W Peak Pulse Zener TVS Diode","metaDescription":"AEC-Q101 qualified Zener TVS diode, 64.1V standoff, 104V clamping, 1500W peak pulse, DO-214AB SMC surface mount.
