It switches a 28 V max load at up to 3 A continuous, with a typical on-resistance of 40 mOhm that keeps conduction losses manageable in a compact footprint. The switch is self-protected with fixed current limiting and over-temperature shutdown, so it can drive resistive, inductive, or lamp loads in harsh environments without an external sense resistor or thermal fuse. ## Obsolete — sourcing and replacement planning If you are qualifying a replacement, look for a low-side switch in a D-Pak or compatible TO-252 footprint with a similar Rds(on) and protection set. The fixed current limit and 150°C TJ rating narrow the candidate pool; many newer parts offer adjustable current limiting but may need an external resistor. ## Parametric profile for fit assessment Output configuration is low-side with a non-inverting On/Off interface — a logic-high on the input turns the N-channel FET on. No Vcc supply is required; the gate is driven from the load voltage internally. The single output is rated 3 A maximum continuous with a 1:1 input-to-output ratio. Fixed current limiting and over-temperature protection are built in; there is no adjustable current-limit pin.","metaTitle":"IPS1031RTRLPBF Low-Side Switch, 40 mOhm, 3 A, D-Pak","metaDescription":"IPS1031RTRLPBF is an obsolete low-side N-channel power switch rated 28 V load, 3 A output, 40 mOhm Rds(on).","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)":"40mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Obsolete","Voltage - Load":"28V (Max)","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"1","Base Product Number":"IPS1031","Output Configuration":"Low Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"3A","Supplier Device Package":"D-Pak","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e511a540bc491de4d9ea80dc7725ba96.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS1031RTRLPBF/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IPS1031RTRLPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IPS1031RTRLPBF when reusing this data.
