Typical Rds(on) is 45 mOhm, and the switch can deliver up to 2.8 A continuous output current. It includes fixed current limiting and over-temperature fault protection, so it handles short circuits and thermal overload without external clamp diodes in most applications. ## Parametric fit for automotive and industrial rails The 35 V max load voltage covers 12 V and 24 V nominal systems with headroom for load-dump transients. The 2.8 A output at 45 mOhm typical Rds(on) means conduction losses stay under 0.35 W at full load — manageable with the D²Pak exposed tab soldered to a copper plane. Input is non-inverting with a simple on/off interface — no external Vcc supply required. The 1:1 input-to-output ratio means the gate is driven directly from the logic signal, simplifying the BOM for relay, solenoid, lamp, and motor pre-drive stages. ## Obsolete — sourcing through independent channel","metaTitle":"IPS031S Low-Side Switch, 45 mOhm, 2.8 A, Obsolete","metaDescription":"IPS031S low-side N-channel power switch: 45 mOhm Rds(on), 2.8 A output, 35 V max load, -40°C to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Features":"-","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"45mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","Voltage - Load":"35V (Max)","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"1","Base Product Number":"IPS031","Output Configuration":"Low Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"2.8A","Supplier Device Package":"D2PAK","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/684d81593e30ba5b1984420e73e31e95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS031S/alternatives.json"},"ai":{"faq":[{"question":"Is IPS031S obsolete?","answer":"Yes, the IPS031S is listed as obsolete.
