Its 50 mOhm typical Rds(on) at 25°C sets the conduction loss floor: at 7A continuous output, that's about 2.5W dissipation before you even account for the package's thermal resistance to the board. The switch handles a load voltage range of 5V to 34V and needs no external Vcc supply — the gate drive is self-biased from the load pin. That simplifies the BOM for a 12V or 24V automotive rail. ## Fault protection — what the scorch mark won't show This part packs eight fault protections: current limiting (fixed), open-load detect, over-temperature, over-voltage, reverse battery, reverse current, short-circuit, and UVLO. When a lamp filament shorts or a solenoid coil welds, the switch shuts itself off and auto-restarts once the fault clears — no external watchdog needed. The slew-rate controlled turn-on reduces EMI from inrush currents on capacitive loads like incandescent bulbs or motor start caps. The logic-level input is non-inverting, so a high on the IN pin turns the output on. ## 150°C junction — engine-bay and industrial thermal cycling The TO-263-5 package with its exposed tab lets you pull heat into a PCB copper pour or an external heatsink.","metaTitle":"Infineon BTS426L1E3062A PROFET High-Side Switch, 50 mOhm","metaDescription":"Infineon BTS426L1E3062A PROFET high-side switch, 50 mOhm typical Rds(on), 7A max output, -40°C to 150°C TJ, TO-263-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"PROFET®","Package":"Bulk","Features":"Auto Restart, Slew Rate Controlled","Interface":"Logic","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"50mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-263-5, D²Pak (4 Leads + Tab), TO-263BB","Product Status":"Active","Voltage - Load":"5V ~ 34V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage, Reverse Battery, Reverse Current, Short Circuit, UVLO","Number of Outputs":"1","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"7A","Supplier Device Package":"PG-TO263-5-2","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e601beabe39aaee408ac554fb1266408.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Rds(on) of the BTS426L1E3062A?","answer":"The typical on-resistance is 50 mOhm at 25°C.
