With a typical Rds(on) of 160 mOhm and a maximum continuous output current of 1.8 A, it suits solenoid valves, relays, incandescent bulbs, and small DC motors where conduction loss and thermal rise must stay within the D²Pak package's dissipation capability. ## Integrated fault protection reduces external BOM The switch integrates fixed current limiting, open-load detection, overtemperature shutdown, overvoltage clamping, and undervoltage lockout (UVLO), eliminating the need for discrete protection components on each output channel. The Auto Restart feature means the device attempts to re-enable after a fault condition clears, which is useful for transient overloads but requires the system designer to account for repeated fault cycling in the thermal budget. ## NRND — sourcing reality for this PROFET It remains available for existing production runs through independent distribution, but new BOM insertions should evaluate the current-generation PROFET portfolio for a drop-in or near-drop-in replacement.","metaTitle":"BTS409L1E3062ABUMA1 PROFET high-side switch, 160 mOhm, 1.8A","metaDescription":"Infineon BTS409L1E3062ABUMA1 PROFET single high-side switch, 160 mOhm Rds(on), 1.8A max output, 5V-34V load range, -40°C to 150°C, NRND.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"PROFET®","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Auto Restart","Interface":"On/Off","Input Type":"-","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":"Not For New Designs","Voltage - Load":"5V ~ 34V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage, UVLO","Number of Outputs":"1","Base Product Number":"BTS409","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":"$3.6700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7860bb04d7a4943c776259d1f256e9d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BTS409L1E3062ABUMA1 obsolete?","answer":"It is not fully discontinued, but the manufacturer advises against using it in new designs.
