It switches loads from 4.5V up to 28V, making it a fit for 12V and 24V automotive and industrial systems — lamp banks, solenoid drivers, relay coils, and small motor loads. ## 21 mOhm Rds(on) and integrated fault protection The 21 mOhm typical Rds(on) keeps conduction losses low at full load — at 5.4A the dissipation is under 0.6W per channel, manageable in the SO-20 wide-body package with adequate PCB copper. The built-in fault protection covers current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping, so the switch handles shorted loads and inductive kickback without external clamp diodes. ## Temperature grade and operating envelope The load supply spans 4.5V to 28V, covering nominal 12V and 24V rails with margin for transients. The BTS5240GNT carries an obsolete lifecycle status.","metaTitle":"Infineon BTS5240GNT Dual High-Side Switch, 5.4A, 21mOhm","metaDescription":"Infineon BTS5240GNT dual high-side power switch, 2 outputs at 5.4A max, 21mOhm Rds(on), 4.5V–28V 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)":"21mOhm","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Obsolete","Voltage - Load":"4.5V ~ 28V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"2","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"5.4A","Supplier Device Package":"PG-DSO-20-21","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e195a8ce0be46a066809e2ce12496aab.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BTS5240GNT?","answer":"BTS5240GNT is obsolete and sourced through independent distribution."},{"question":"What is the replacement for BTS5240GNT?","answer":"For a cross-reference, review Infineon's current PROFET™ family for a functional equivalent with similar current rating and package footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BTS5240GNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BTS5240GNT when reusing this data.
