The device can sink up to 100 mA continuous, limited by package dissipation in the SC-70-6. The SC-70-6 package (also designated SOT-363) keeps the footprint small for dense layouts.","metaTitle":"TL431QDCKT Shunt Voltage Reference, ±2.2% Tolerance, Active","metaDescription":"Texas Instruments TL431QDCKT adjustable shunt reference, ±2.2% tolerance, 100 mA output, SC-70-6 package.

This sets the accuracy of the output voltage set by the external resistor divider."},{"question":"Is TL431QDCKT compatible with TL431B?","answer":"The TL431QDCKT is a specific grade of the TL431 family. The TL431B typically offers a tighter tolerance (e.g., ±0.5%), but both are adjustable shunt references with the same functional pinout and operating range. The QDCKT suffix indicates the SC-70-6 package. For a drop-in replacement, confirm the tolerance grade your design requires."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431QDCKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431QDCKT when reusing this data.
