When a surge hits, breakdown starts at 28.9 V min and the diode clamps the transient to 42.1 V max at 11.9 A, shunting the energy away from the downstream circuitry. The single bidirectional channel clamps both positive and negative spikes — one component replaces two unidirectional TVS diodes in anti-series, saving placement cost and board area. ## Junction temperature and package — the thermal reality That covers military and automotive extremes — the diode does not derate until the ambient forces the junction above 150°C. In practice, the DO-214AC (SMA) package relies on the PCB copper pad area under the cathode tab to pull heat out; a 1 oz copper pad with at least 30 mm² of copper area keeps the junction within limits during repetitive surge events. Surface-mount assembly on a standard reflow profile. Microchip lists the SMAJ26CAE3/TR13 as Active. The base product number is SMAJ26, so any future PCN or LTB will reference that base.","metaTitle":"SMAJ26CAE3/TR13 TVS Diode – 26V Bidirectional, 500W","metaDescription":"SMAJ26CAE3/TR13 Zener TVS, 26V reverse standoff, 28.9V min breakdown, 42.1V clamp at 11.9A. 500W peak pulse, DO-214AC (SMA), -65°C to 150°C.","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","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 SMAJ26CAE3/TR13 bidirectional?","answer":"Yes — it has one bidirectional channel.
