With a 5 V reverse standoff voltage and a 6.4 V minimum breakdown voltage, it clamps transients to 9.2 V maximum at the 43.5 A peak pulse current (10/1000 µs waveform). The 400 W rating means it can absorb a single 10/1000 µs surge up to that power level without failing — a common benchmark for protecting 5 V logic, data lines, and low-voltage supply rails in general-purpose equipment. ## DO-214AC footprint and board integration The DO-214AC (SMA) package with the supplier device package code SMA is a compact two-terminal footprint common for TVS diodes in this power class. The surface-mount body sits low on the PCB, and the copper pad area under the cathode tab sets the thermal impedance — a larger pad improves heat spreading during repetitive surge events. The -55°C to 150°C junction temperature range covers industrial and outdoor enclosures where ambient temperatures swing widely.","metaTitle":"SMAJ5.0A-13 Diodes Inc TVS Diode, 400W, 5V Standoff","metaDescription":"SMAJ5.0A-13 400W unidirectional TVS diode in DO-214AC (SMA) package. 5V reverse standoff, 6.4V breakdown, 9.2V clamping at 43.5A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","lifecycle_stage":"eol_hot","Power - Peak Pulse":"400W","Base Product Number":"SMAJ5.0","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMA","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.4V","Voltage - Clamping (Max) @ Ipp":"9.2V","Voltage - Reverse Standoff (Typ)":"5V","Current - Peak Pulse (10/1000µs)":"43.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a6e414533ed6f0f7c15ae6d19d66ae3c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is SMAJ5.0A-13's listed type and package?","answer":"The SMAJ5.0A-13 is a Zener-type TVS diode in a DO-214AC (SMA) surface-mount package, supplied on Tape & Reel or Cut Tape.
