The clamping voltage maxes out at 14.5 V at the peak pulse current of 690 A (8/20 µs), so the protected rail sees a hard ceiling well below the absolute maximum of most 5 V logic. ## Breakdown and standoff — picking the right voltage tier Reverse standoff voltage is 6.4 V, meaning the diode stays off below that level. Breakdown starts at a minimum of 7.13 V. ## DO-214AB SMC — rework and footprint notes It reworks cleanly with hot air — the body is large enough to get a good grip with tweezers, and the cathode band is clearly marked on the top. No exposed pad underneath, so you don't need a bottom-side preheater. Just watch the soldering profile; the junction can handle 150 °C continuous, so standard lead-free reflow is fine. ## Active and available — no LTB worry STMicroelectronics lists the SM15T7V5A as an active product. That means it stays in the BOM for new designs without a sunset date looming.","metaTitle":"STMicro SM15T7V5A TVS Diode, 1500W, DO-214AB SMC","metaDescription":"STMicroelectronics SM15T7V5A TRANSIL™ TVS, 1500W peak pulse power, 6.4V standoff, 7.13V breakdown, unidirectional, DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"SM15T, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"SM15T7V5","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"7.13V","Voltage - Clamping (Max) @ Ipp":"14.5V","Voltage - Reverse Standoff (Typ)":"6.4V","Current - Peak Pulse (10/1000µs)":"690A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4573","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/539ce92ad6505c8a9d704773ec1ef151.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM15T7V5A/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between unidirectional and bidirectional TVS?","answer":"The SM15T7V5A is a unidirectional TVS, meaning it clamps transients in only one polarity (positive relative to ground). A bidirectional TVS clamps both positive and negative transients, typically used on AC lines or signal pairs where the voltage swings both ways. For a DC power rail, unidirectional is the correct choice."},{"question":"Is SM15T7V5A RoHS compliant?","answer":"The part is listed with Tape & Reel and Cut Tape packaging options, which are typically RoHS-compliant from STMicroelectronics.
