No official replacement part is listed on the record. ## 35 mOhm Rds(on) — conduction loss and thermal budget Typical on-resistance of 35 mOhm sets the conduction loss floor for the high-side switch. At 8.8 A maximum output, the resistive loss at full load is roughly 2.7 W, which the TO-263-5 (D²Pak) package must dissipate — the large exposed tab on PG-TO263-5-2 helps sink heat to the PCB copper plane. Rds(on) increases with junction temperature; the 150 °C maximum junction rating means derating is required at high ambient temperatures typical of under-hood or industrial enclosures. ## 4.75 V to 41 V load supply, 8.8 A output — power distribution envelope The load voltage range spans 4.75 V to 41 V, covering standard automotive battery rails (12 V, 24 V) and industrial 48 V systems with margin. The 8.8 A continuous output rating supports loads such as relays, solenoids, lamps, and small motors. As a high-side configuration with a 1:1 input-to-output ratio, the switch connects the load to the supply rail when the non-inverting input is driven high. No external Vcc supply is required — the gate drive is self-powered from the load voltage. ## Fault protection suite — reduces external supervision circuitry Integrated protections include current limiting (fixed), open load detection, over-temperature shutdown, and over-voltage clamp. The Status Flag output provides a diagnostic signal to the host controller, reducing the need for external sense resistors or comparators. ## Package and mounting — TO-263-5 D²Pak Surface-mount package in TO-263-5 (D²Pak) with 4 leads plus tab, also designated PG-TO263-5-2. The exposed tab is the main thermal path — PCB layout must provide a solid copper pour and vias to the ground plane for adequate heat spreading. Standard reflow profile for MSL-rated D²Pak applies.","metaTitle":"BTS436L2G PROFET high-side switch, 35 mOhm, 8.8 A, obsolete","metaDescription":"Infineon BTS436L2G PROFET high-side power switch, 35 mOhm Rds(on), 8.8 A, 4.75-41 V load, -40 to 150 °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":"PROFET®","Package":"Tape & Reel (TR)","Features":"Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"35mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-263-5, D²Pak (4 Leads + Tab), TO-263BB","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-TO263-5-2","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":"What is the Rds(on) of the BTS436L2G?","answer":"The typical Rds(on) is 35 mOhm.
