The ±0.5% tolerance (B-grade) is tighter than the standard TL431's ±2.2%, which matters when the reference sets the output accuracy of a switching regulator or an ADC reference.","metaTitle":"TL431BQDBZRQ1 Automotive Shunt Reference, ±0.5%, AEC-Q100","metaDescription":"Texas Instruments TL431BQDBZRQ1 adjustable shunt voltage reference, ±0.5% tolerance, 100 mA output, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.5%","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":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","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-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5400","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431BQDBZRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TL431BQDBZRQ1 meet AEC-Q100 qualification?","answer":"Yes, the TL431BQDBZRQ1 is part of the Automotive, AEC-Q100 series, qualified for automotive-grade applications including under-hood and chassis domains."},{"question":"What is the TL431BQDBZRQ1 tolerance and accuracy?","answer":"The TL431BQDBZRQ1 offers ±0.5% tolerance on the 2.495 V reference voltage, which is the B-grade precision level in the TL431 family."},{"question":"What is the maximum output current for TL431BQDBZRQ1?","answer":"The TL431BQDBZRQ1 can sink up to 100 mA as a shunt regulator, limited by the SOT-23-3 package thermal capability."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431BQDBZRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431BQDBZRQ1 when reusing this data.
