The minimum breakdown voltage is 8.33V, which sits about 0.8V above the 7.5V standoff — that gap is the normal leakage region. The clamping voltage at 12.9V max defines the peak voltage the downstream circuitry must survive. For a 5V logic rail, this margin is generous; for a 12V rail, the 12.9V clamp may be tight, so verify the downstream device's absolute maximum rating. Microchip lists the SMAJ7.5AE3/TR13 as Active. That means no last-time-buy window, no successor search needed. The DO-214AC (SMA) package is a surface-mount footprint with a small copper pad area — the thermal resistance depends on the PCB copper pour, so for sustained high-energy pulses, a larger pad helps keep the junction temperature rise within limits.","metaTitle":"SMAJ7.5AE3/TR13 TVS Diode – Microchip, 500W, 7.5V Standoff","metaDescription":"SMAJ7.5AE3/TR13 Zener TVS diode from Microchip Technology. 500W peak pulse power, 7.5V reverse standoff, unidirectional, DO-214AC (SMA).","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":"SMAJ7.5","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)":"8.33V","Voltage - Clamping (Max) @ Ipp":"12.9V","Voltage - Reverse Standoff (Typ)":"7.5V","Current - Peak Pulse (10/1000µs)":"38.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b3ddece4863b4621debe180df56adc8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SMAJ7.5AE3/TR13 and SMAJ7.5A?","answer":"The SMAJ7.5A is the base part number without the /TR13 suffix. The suffix indicates a lead-free / RoHS-compliant finish, and TR13 specifies Tape & Reel packaging. The electrical specs — 7.5V standoff, 500W peak pulse, 12.9V clamp — are identical between the two. If your BOM calls for SMAJ7.5A, the /TR13 variant is a drop-in replacement as long as the package and reel format match your assembly process."},{"question":"Is SMAJ7.5AE3/TR13 RoHS compliant?","answer":"The suffix in the order code indicates a lead-free, RoHS-compliant termination finish.
