Its typical on-resistance of 50 mOhm sets the conduction loss floor: at 5.8 A the dissipation is roughly 1.7 W before any derating for junction temperature. This means Infineon has flagged the part for eventual discontinuation; new designs should not start with it. ## Fault protection suite — what trips and what resets The part integrates fixed current limiting, open-load detection, over-temperature shutdown, over-voltage clamping, and under-voltage lockout (UVLO). The Auto Restart feature means the switch attempts to re-energise after a fault clears — useful for lamp or motor loads where a temporary overload is expected, but something to account for in the system fault-handling logic. Input is a simple On/Off non-inverting logic signal; no Vcc supply is required for the logic side — the switch is self-powered from the load rail. ## TO-263-5 D²Pak — thermal pad and footprint The package is a TO-263-5 (D²Pak) with four leads plus the exposed tab. The supplier device code is PG-TO263-5-2. The 5V to 34V load voltage range covers 12V and 24V automotive and industrial rails, with margin for load-dump transients.","metaTitle":"Infineon BTS426L1E3062ABUMA1 PROFET High-Side Switch","metaDescription":"Infineon BTS426L1E3062ABUMA1 PROFET smart high-side switch, 50 mOhm Rds(on), 5.8 A output, -40°C to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"PROFET®","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Auto Restart","Interface":"On/Off","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":"Not For New Designs","Voltage - Load":"5V ~ 34V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage, UVLO","Number of Outputs":"1","Base Product Number":"BTS426L1","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"5.8A","Supplier Device Package":"PG-TO263-5-2","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.8300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e741feb9c8a8292e9705cb89e4fdbffc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BTS426L1E3062ABUMA1 obsolete?","answer":"It is still available through independent distribution, but Infineon advises against using it in new designs."},{"question":"What is the replacement for BTS426L1E3062ABUMA1?","answer":"A pin-compatible alternative within the PROFET family would need to match the 50 mOhm typical Rds(on), the 5.8 A continuous output rating, and the TO-263-5 package. Validate the replacement against your load profile and fault-protection requirements before committing the BOM."},{"question":"What is the BTS426L1E3062ABUMA1 vs BTS426L1?","answer":"BTS426L1 is the base product number for this PROFET series. The full order code BTS426L1E3062ABUMA1 specifies the exact reel-and-packaging variant (Tape & Reel, Cut Tape). The silicon and the 50 mOhm Rds(on) / 5.8 A ratings are identical across the BTS426L1 base number; the suffix differentiates the shipping format."},{"question":"Is BTS426L1E3062ABUMA1 lead-free?","answer":"The TO-263-5 package is a standard lead-free compatible assembly.
