It switches a resistive or inductive load on the high side with a typical on-resistance of 35 mOhm, rated for a continuous output current up to 8.8 A. The load supply range spans 4.75 V to 41 V, and the switch does not require a separate Vcc supply — it is self-powered from the load voltage. The input is non-inverting with a simple On/Off interface, and the output is an N-channel MOSFET with a 1:1 input-to-output ratio. ## Fault protection and temperature range Built-in fault protection covers current limiting (fixed), open load detection, over-temperature shutdown, and over-voltage clamping. A status flag output signals fault conditions to the system controller. ## Obsolete — sourcing through independent distribution The BTS436L2S carries an Obsolete lifecycle status. Procurement for this part runs through independent distribution and surplus channels. No stock-holding claim is made here — each order is sourced per RFQ.","metaTitle":"Infineon BTS436L2S PROFET High-Side Switch, 35 mOhm","metaDescription":"Infineon BTS436L2S PROFET high-side power switch, 35 mOhm Rds(on), 8.8 A output, TO-220-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"PROFET®","Package":"Tube","Features":"Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"35mOhm","Mounting Type":"Through Hole","Package / Case":"TO-220-5","Product Status":"Obsolete","Voltage - Load":"4.75V ~ 41V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS436L2","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"8.8A","Supplier Device Package":"PG-TO220-5-12","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f675fa41cc463e49d20506c50b5d71e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BTS436L2S?","answer":"The BTS436L2S is obsolete and sourced through independent distribution.
