At 13.5 A maximum continuous output current, the conduction loss is the thermal load the TO-220AB package must dissipate. ## Built-in fault protection Fixed current limiting and over-temperature shutdown are integrated — no external sense resistor or comparator needed. The current limit clamps the output at a fixed threshold; if the junction exceeds the thermal trip point, the switch latches off until it cools. This makes the part suitable for driving resistive, inductive, or lamp loads in harsh industrial environments where fault conditions are expected. ## Package and mounting — TO-220AB The through-hole TO-220AB package (3-lead) has a metal tab for heatsink attachment. The tab is electrically connected to the drain (output) — an insulating pad and washer are needed if the heatsink is grounded. The mounting hole accepts a standard M3 screw; torque to the datasheet specification to avoid cracking the plastic body.","metaTitle":"IPS1021PBF Low-Side Switch, 20 mOhm, 13.5 A, TO-220","metaDescription":"IPS1021PBF low-side N-channel power switch, 20 mOhm Rds(on), 13.5 A max, TO-220AB, -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":"Tube","Features":"-","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"20mOhm","Mounting Type":"Through Hole","Package / Case":"TO-220-3","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":"IPS1021","Output Configuration":"Low Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"13.5A","Supplier Device Package":"TO-220AB","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f10c3f059773e7a4a60b663d9094e96b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS1021PBF/alternatives.json"},"ai":{"faq":[{"question":"Can I still buy IPS1021PBF?","answer":"Yes — while the part is obsolete from the manufacturer, it is available to source through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IPS1021PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IPS1021PBF when reusing this data.
