It integrates a 150 mOhm typical Rds(on) power MOSFET with a 12V to 45V load voltage range and delivers up to 700 mA continuous output current. The switch is self-protected with fixed current limiting, over-temperature shutdown, and over-voltage clamping, and it features an auto-restart function that re-enables the output after a fault condition clears. The 12V to 45V load supply covers standard 12V and 24V industrial rails and 24V/48V automotive nominal buses, but the 45V absolute maximum means the switch cannot survive a 48V truck system without external clamping. The 700 mA continuous output current is the DC limit; for pulsed or lamp-inrush loads the internal current limiting (fixed) will fold back the output, so the load must be sized to stay below the trip threshold during steady-state. ## Obsolete — finding a replacement The BTS4141NNT is officially listed as obsolete. Any candidate should match the output configuration (high-side, N-channel), the load voltage range, the 700 mA current rating, and the SOT223 footprint if a drop-in is required. The auto-restart feature is not universal among high-side switches, so designs that rely on it may need a logic change or a different fault-handling strategy.","metaTitle":"BTS4141NNT Infineon High-Side Power Switch, 150 mOhm, 700 mA","metaDescription":"Infineon BTS4141NNT high-side power switch, 150 mOhm Rds(on), 700 mA output, 12V-45V load, PG-SOT223-4.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","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-261-4, TO-261AA","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-SOT223-4","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a19288467bf3b6f0ffd566b9bada5bbc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is a suitable replacement for BTS4141NNT?","answer":"No official replacement is listed for this order code. A suitable replacement must match the high-side N-channel output, 12V to 45V load range, 700 mA current rating, and PG-SOT223-4 package for a drop-in. The auto-restart feature is not common, so designs that depend on it may need a logic change.
