It integrates an N-channel MOSFET with a typical on-resistance of 150 mOhm and delivers up to 700 mA continuous output current. The switch is controlled by a simple On/Off interface with non-inverting input logic, and requires no external Vcc supply — the gate drive is self-supplied from the load voltage. ## Fault protection and auto-restart behaviour Built-in fault protection covers fixed current limiting, over-temperature shutdown, and over-voltage clamping — the device survives shorted loads and thermal runaway without external clamp diodes. The Auto Restart feature means the switch attempts to re-enable after a fault condition clears, which is useful for intermittent loads like solenoids or bulbs where a temporary overload is expected. Housed in a PG-TO252-5-1 (DPak) surface-mount package with four leads plus a tab for thermal dissipation.","metaTitle":"BTS4141D Infineon miniPROFET High-Side Switch, 150 mOhm","metaDescription":"Infineon BTS4141D miniPROFET high-side power switch, 150 mOhm Rds(on), 700 mA max output, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"miniPROFET®","Package":"Tape & Reel (TR)","Features":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"150mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-252-5, DPak (4 Leads + Tab), TO-252AD","Product Status":"Obsolete","Voltage - Load":"12V ~ 45V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS4141","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 125°C (TJ)","Current - Output (Max)":"700mA","Supplier Device Package":"PG-TO252-5-1","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f45ea6e93db25964cce6c2a2fd18ceda.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BTS4141D/alternatives.json"},"ai":{"faq":[{"question":"Is BTS4141D obsolete?","answer":"Yes, Infineon lists the BTS4141D as obsolete.
