This tighter grade (B suffix) makes it the choice for precision power-supply feedback loops, error amplifiers, and reference circuits where the standard 1% or 2% grades leave too little margin. The 100 mA cathode current rating sets the maximum load the shunt can sink, which directly sizes the bias resistor and the power dissipation in the SC-70-6 package. ## SC-70-6 package and thermal considerations The 600 µA minimum cathode current ensures the shunt stays in regulation even at light load.","metaTitle":"TL431BCDCKT Shunt Voltage Reference, ±0.5% Tolerance","metaDescription":"Texas Instruments TL431BCDCKT adjustable shunt voltage reference, ±0.5% tolerance, 100 mA output, SC-70-6 package.","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); Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"600 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"0°C~70°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SC-70-6","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431BCDCKT/alternatives.json"},"ai":{"faq":[{"question":"Is the TL431BCDCKT RoHS compliant?","answer":"The TL431BCDCKT is listed with a Tape & Reel and Cut Tape packaging option, and as a Texas Instruments lead-free device it is RoHS compliant per standard industry practice."},{"question":"Can the TL431BCDCKT be used in automotive applications?","answer":"For automotive designs, consider the TL431A-Q1 or TL431B-Q1 AEC-Q100 qualified variants."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431BCDCKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431BCDCKT when reusing this data.
