It integrates an N-channel MOSFET with a 190 mOhm typical Rds(on) and delivers up to 1.6 A continuous output current over a load supply range of 4.7 V to 42 V. Built-in fault protection — current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping — reduces the need for external clamp diodes or sense resistors. At 1.6 A and 190 mOhm, the conduction loss is I²R ≈ 0.49 W at 25°C junction. The TO-220-5 through-hole package with a copper pad on the tab can dissipate that in free air, but at 150°C junction the Rds(on) roughly doubles — budget closer to 1 W loss at temperature. The 42 V load maximum gives headroom for 24 V nominal systems with load-dump transients, though the part itself clamps over-voltage. The 1:1 input-to-output ratio and On/Off interface simplify the gate drive: no external charge pump or level shifter is needed because the logic-level input is non-inverting and the supply voltage Vcc is not required — the switch is self-biased from the load supply. Status flag output feeds a microcontroller GPIO for diagnostic readback. ## Obsolete — sourcing through independent distribution Infineon lists the BTS410E2E3043NKSA1 as obsolete.","metaTitle":"Infineon BTS410E2E3043NKSA1 PROFET High-Side Switch","metaDescription":"Infineon BTS410E2E3043NKSA1 PROFET high-side switch, 1.6 A output, 190 mOhm Rds(on), 4.7-42 V load, 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":"Auto Restart, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"190mOhm","Mounting Type":"Through Hole","Package / Case":"TO-220-5","Product Status":"Obsolete","Voltage - Load":"4.7V ~ 42V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS410E2","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"1.6A","Supplier Device Package":"P-TO220-5-43","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b82f6c865867b48a26b9846c63bde67f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BTS410E2E3043NKSA1?","answer":"No official replacement order code is recorded in the available lifecycle data.
