Rated for 500W peak pulse power under the 10/1000 µs waveform, it handles 18.8A peak pulse current — enough for typical industrial and telecom board-level protection where the fault energy is limited by upstream fusing or PTCs. ## DO-214AC rework and footprint reality The SMA footprint is forgiving under a hot-air station: the pads are large enough to wet with a fine-tip iron, and the body thermal mass is low, so a 300°C hot-air profile at low flow lifts the part cleanly without cooking adjacent passives. Operating temperature spans -65°C to 150°C junction, so the part survives reflow profiles (peak 260°C) and field extremes from cold outdoor enclosures to hot motor-drive cabinets. ## Active production, Tape & Reel supply Sourced through our distribution channel against an RFQ. The base product number SMAJ15 covers the family; the /TR13 variant is the reeled, RoHS-compliant version.","metaTitle":"SMAJ15E3/TR13 TVS Diode, 15V Standoff, 500W","metaDescription":"SMAJ15E3/TR13 Zener TVS diode from Microchip Technology. 15V reverse standoff, 26.9V clamp, 500W peak pulse power, unidirectional, DO-214AC (SMA) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SMAJ15","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"16.7V","Voltage - Clamping (Max) @ Ipp":"26.9V","Voltage - Reverse Standoff (Typ)":"15V","Current - Peak Pulse (10/1000µs)":"18.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b3ddece4863b4621debe180df56adc8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SMAJ15E3/TR13 bidirectional?","answer":"No — it is a unidirectional Zener TVS with one channel.
