Rated for 100 mA continuous cathode current and requiring only 1 mA to regulate, it suits both low-power bias circuits and higher-current shunt regulators in industrial and automotive environments spanning -40°C to 125°C. Stock is limited to independent-distributor and surplus inventories. ## Key ratings that decide the fit The 2.495 V internal reference has a ±2.2% tolerance. 100 mA output current defines the maximum load the shunt can sink before the pass element saturates; for designs drawing more than that, a higher-current TL431 variant or an external boost transistor is needed. The SOT-23-5 footprint is compact but limits power dissipation — the 125°C junction maximum means the thermal resistance of the board layout sets the practical derating.","metaTitle":"TL431QDBVTE4 Shunt Reference, 2.495V, ±2.2%, Obsolete","metaDescription":"Texas Instruments TL431QDBVTE4 adjustable shunt reference, 2.495V min output, ±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/TL431QDBVTE4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431QDBVTE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431QDBVTE4 when reusing this data.
