The three leads are clearly spaced, and the package outline leaves room for probe access. No exposed pad means no thermal solder-paste stencil concerns — just a standard footprint with a small copper land pattern.","metaTitle":"TL432BQDBZRG4 Shunt Voltage Reference, ±0.5% Tolerance","metaDescription":"Texas Instruments TL432BQDBZRG4 adjustable shunt reference, ±0.5% tolerance, 100 mA output, -40°C to 125°C, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","Base Product Number":"TL432","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":"$0.5600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432BQDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the accuracy (tolerance) of TL432BQDBZRG4?","answer":"The tolerance is ±0.5%, which is tighter than the standard TL431 family's typical ±1% to ±2% grades. This matters for precision feedback loops where reference voltage drift directly affects output regulation."},{"question":"Is TL432BQDBZRG4 a good replacement for TL431?","answer":"Yes, the TL432BQDBZRG4 is pin-compatible with the TL431 in the same SOT-23-3 package and shares the same adjustable shunt reference function. The key difference is the tighter ±0.5% tolerance versus the TL431's typical wider tolerance — so it is a drop-in upgrade for designs needing better accuracy."},{"question":"What is the maximum current output of TL432BQDBZRG4?","answer":"The maximum cathode current is 100 mA. This sets the drive capability for optocoupler LEDs in feedback loops or for biasing other circuitry. The 700 µA minimum cathode current ensures the device stays in regulation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432BQDBZRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432BQDBZRG4 when reusing this data.
