Peak pulse power is rated at 500W for a 10/1000µs waveform, with a clamping voltage of 42.1V at 11.9A peak pulse current. Housed in a DO-214AC (SMA) package, surface-mount, supplied on tape & reel. ## Sizing the clamp for your surge budget The 500W peak pulse power is the headline surge rating — but it's specified at a 10/1000µs waveform. If your transient is shorter (e.g. 8/20µs), the part can absorb more peak current; if longer, derate accordingly. The 11.9A peak pulse current is the limit at that waveform. Keep it on DC rails under 26V. ## Active production — no last-time-buy rush Microchip lists the SMAJ26AE3/TR13 as Active. For a storeroom keeper, that means you can order this part for the next several years without a last-time-buy scramble. Supplied on tape & reel — store the reels in a dry cabinet if the ambient humidity is above 60% RH; the DO-214AC body is not moisture-sensitive per JEDEC Level 1, but the carrier tape can absorb moisture over long storage.","metaTitle":"SMAJ26AE3/TR13 Zener TVS Diode – 26V, 500W, DO-214AC","metaDescription":"SMAJ26AE3/TR13 Zener TVS diode from Microchip Technology. 26V reverse standoff, 28.9V breakdown, 500W peak pulse power, 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":"SMAJ26","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)":"28.9V","Voltage - Clamping (Max) @ Ipp":"42.1V","Voltage - Reverse Standoff (Typ)":"26V","Current - Peak Pulse (10/1000µs)":"11.9A"}},"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 SMAJ26AE3/TR13 RoHS compliant?","answer":"The evidence does not list a RoHS compliance statement. Microchip typically marks RoHS-compliant parts with an '' suffix in the order code — this part carries that suffix (in SMAJ26AE3/TR13), which is their standard RoHS indicator. Confirm with the datasheet or your Microchip rep for formal certification."},{"question":"What is the closest pin-compatible alternative to SMAJ26AE3/TR13?","answer":"The base product number is SMAJ26. Microchip offers the same die in different packaging or screening levels (e.g., SMAJ26A, SMAJ26AE3). Any DO-214AC Zener TVS with 26V standoff and 500W rating from another brand (e.g., Littelfuse, Vishay) is a functional cross, but pinout and footprint are identical across the SMA package standard. Verify the breakdown voltage tolerance and clamping spec against your design margin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ26AE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ26AE3-TR13 when reusing this data.
