The 160 mOhm typical Rds(on) sets the conduction loss floor: at 1.8 A the dissipation is about 0.5 W, which the PG-TO263-5-2 package's exposed tab sinks to the board copper. The 160 mOhm typical on-resistance is the value at 25°C junction; expect it to roughly double at 150°C junction. If the load draws 1.8 A continuously, the I²R loss at temperature could reach 1 W — that copper area on the PG-TO263-5-2 tab needs to be generous. The part includes over-temperature shutdown, so a marginal heatsink causes cycling rather than immediate failure, but the thermal pad layout should still follow the datasheet's recommended footprint. ## Obsolete — sourcing this part today The BTS409L1 E3062A carries an Obsolete lifecycle status.","metaTitle":"BTS409L1 E3062A PROFET High-Side Switch, 160 mOhm, Obsolete","metaDescription":"Infineon BTS409L1 E3062A PROFET high-side power switch, 1.8 A output, 160 mOhm Rds(on), 5-34 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); Cut Tape (CT)","Features":"Auto Restart, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"160mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-263-5, D²Pak (4 Leads + Tab), TO-263BB","Product Status":"Obsolete","Voltage - Load":"5V ~ 34V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS409L1","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"1.8A","Supplier Device Package":"PG-TO263-5-2","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.5400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7860bb04d7a4943c776259d1f256e9d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BTS409L1 E3062A obsolete?","answer":"Yes, the BTS409L1 E3062A is listed as Obsolete.
