It switches grounded loads up to 2.8 A from a supply rail rated to 35 V maximum, with a typical on-resistance of 45 mOhm. The switch is controlled by a simple On/Off logic input (non-inverting, 1:1 ratio) and requires no external Vcc supply — the gate drive is self-biased from the load voltage. ## 45 mOhm Rds(on) and 150°C junction rating The 45 mOhm typical Rds(on) keeps conduction losses low — at 2.8 A the I²R loss is about 0.35 W, manageable in the D2PAK footprint with adequate PCB copper for heat sinking. The 35 V maximum load voltage covers 12 V and 24 V nominal systems with headroom for load-dump transients in automotive environments. For a pin-compatible replacement, the IPS031S family (base product number IPS031S) includes similar-function devices — verify the specific variant and ratings against your BOM before substituting.","metaTitle":"IPS031STRR Low-Side Switch, 2.8A, 35V, D2PAK, Obsolete","metaDescription":"IPS031STRR single-channel low-side power switch, 45 mOhm Rds(on), 2.8A max output, 35V load, -40°C 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":"-","Package":"Tape & Reel (TR)","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":"IPS031S","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/e92925b9c025be945dbad2412d902545.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS031STRR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for IPS031STRR?","answer":"The base product number IPS031S covers a family of low-side switches — a similar-function variant within that family may be pin-compatible, but you must verify the specific ratings (current, voltage, Rds(on), protection features) against your BOM before substituting."},{"question":"What are the specifications of IPS031STRR?","answer":"It is a single-channel low-side N-channel power switch in a D2PAK package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IPS031STRR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IPS031STRR when reusing this data.
