Its 19 mOhm typical Rds(on) keeps conduction losses low in a 12 V automotive or industrial power distribution rail. The switch integrates fixed current limiting, open-load detection, and over-temperature shutdown — three fault protections that reduce external sense circuitry and simplify the BOM for rugged applications. At 3.5 A, the 19 mOhm typical on-resistance produces about 233 mW of I²R loss. The Rds(on) is specified at 25 °C junction; actual resistance rises with temperature per the normalised curve in the datasheet, so derate the continuous current if the ambient exceeds 85 °C or the PCB copper area is limited. Availability is limited to surplus inventory, factory overstock, and broker-channel lots. Sourcing this part requires a verified surplus supplier. We quote each lot individually against an RFQ — the date-code spread, packaging condition (sealed reels or Tube), and quantity available are confirmed at quote time. ## Package and footprint — D²Pak (TO-263-5) with exposed tab The IPS5451S is supplied in a TO-263-5 (D²Pak) package with 4 leads plus a tab. The package ships in Tube form. For reflow assembly, the moisture sensitivity level (MSL) should be verified from the latest Infineon product information — the tab solder joint carries the output current and requires a full fillet.","metaTitle":"IPS5451S high-side switch, 19 mOhm, 3.5 A, obsolete","metaDescription":"IPS5451S high-side N-channel power switch, 19 mOhm Rds(on), 3.5 A output, 5.5-18 V load range.","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":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"19mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-263-5, D²Pak (4 Leads + Tab), TO-263BB","Product Status":"Obsolete","Voltage - Load":"5.5V ~ 18V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature","Number of Outputs":"1","Base Product Number":"IPS5451","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"3.5A","Supplier Device Package":"D2Pak (SMD-220 5-Lead)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a06ca89ca70bc764d6aca042eed932e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS5451S/alternatives.json"},"ai":{"faq":[{"question":"Where can I find the IPS5451S datasheet?","answer":"The IPS5451S datasheet is available from Infineon's product archive.
