Rated for 100 mA continuous cathode current with a minimum bias of 1 mA, it covers the typical load range for shunt references in feedback loops and precision dividers. For existing BOM lines, availability is limited to independent distribution and surplus inventory — quoted to order against the specific quantity required. The TL431QDBVRE4 is supplied in a SOT-23-5 package (also designated SC-74A), with a Tape & Reel shipping medium. The small body and 0.95 mm lead pitch make it hand-solderable with a fine-tip iron; the low thermal mass means it reflows cleanly under hot air without cooking adjacent components.","metaTitle":"TL431QDBVRE4 Adjustable Shunt Reference, ±2.2%, SOT-23-5","metaDescription":"Texas Instruments TL431QDBVRE4 adjustable shunt voltage reference, ±2.2% tolerance, 100 mA output, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431QDBVRE4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TL431QDBVRE4?","answer":"No official successor is listed on the lifecycle record."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431QDBVRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431QDBVRE4 when reusing this data.
