It protects a downstream load rail from overcurrent and overvoltage faults without the thermal reset lag of a PTC or the BOM count of a discrete protector. Rated for a continuous output of 5.3 A across a 2.7 V to 18 V input range, it covers the common automotive supply rails — 3.3 V, 5 V, and 12 V — in a single footprint. The ±8% current-limit accuracy means you size the load budget with a tighter guard band than a PTC's ±30% tolerance allows. ## 125°C operating ceiling — under-hood ready That covers under-hood, engine-bay, and transmission-mounted electronics where the ambient near the ECU or junction box can hit 105°C and the self-heating of the eFuse adds another 20°C. The 20-WFQFN exposed pad pulls heat into the PCB copper pour — the board layout sets the effective thermal resistance, not the package alone. That means no last-time-buy notice to track, no end-of-life scramble for a pin-compatible swap.","metaTitle":"TPS259401AQRVCRQ1 eFuse, Automotive AEC-Q100, 5.3 A","metaDescription":"Texas Instruments TPS259401AQRVCRQ1 electronic fuse, 2.7 V to 18 V input, 5.3 A output, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±8%","Function":"Electronic Fuse","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN Exposed Pad","Product Status":"Active","Sensing Method":"-","Voltage - Input":"2.7V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"5.3A","Base Product Number":"TPS259401","Operating Temperature":"-40°C~125°C","Supplier Device Package":"20-WQFN (4x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0300","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS259401AQRVCRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS259401AQRVCRQ1 suitable for automotive applications?","answer":"Yes.
