In a typical feedback circuit, the designer picks the cathode resistor so that the current through the device stays between 600 µA and 15 mA across all load and line conditions. Dropping below 600 µA risks losing regulation; exceeding 15 mA pushes the junction temperature beyond the rated limit at high ambient. For BOM lines that require a second-source option, the LM4132AMF-4.1/NOPB is a series reference with tighter tolerance (±0.05%) and fixed 4.096 V output, but it is not a direct pin-for-pin replacement — the TL431 is a shunt topology, the LM4132 is a series topology. If the design needs a shunt reference with AEC-Q100 qualification, this part is the current-production choice.","metaTitle":"TL431LIAEDBZRQ1 Automotive AEC-Q100 Shunt Reference, ±1%","metaDescription":"TL431LIAEDBZRQ1 adjustable shunt voltage reference, AEC-Q100 qualified, ±1% tolerance, -40°C to 150°C, SOT-23-3.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"600 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~150°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9200","priceTiers":[{"qty":1,"price":"$0.92000","currency":"USD"},{"qty":10,"price":"$0.82200","currency":"USD"},{"qty":25,"price":"$0.78040","currency":"USD"},{"qty":100,"price":"$0.64120","currency":"USD"},{"qty":250,"price":"$0.59936","currency":"USD"},{"qty":500,"price":"$0.52968","currency":"USD"},{"qty":1000,"price":"$0.41817","currency":"USD"},{"qty":3000,"price":"$0.39450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/960725404a96d9b0e89f219adcdedfe0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431LIAEDBZRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TL431LIAEDBZRQ1 AEC-Q100 qualified?","answer":"Yes, the TL431LIAEDBZRQ1 is part of the Automotive, AEC-Q100 series, qualified for automotive-grade applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431LIAEDBZRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431LIAEDBZRQ1 when reusing this data.
