The 700 µA minimum cathode current keeps the device biased in its linear region across the load range. ## Industrial temperature grade and SOT-323-6L footprint The SOT-323-6L package (also listed as 6-TSSOP/SC-88/SOT-363) occupies roughly 2.1 mm × 2.1 mm board area. At 100 mA cathode current, the package dissipation is about 350 mW; the copper pad area under the device sets the effective thermal resistance, so keep the ground-plane connection generous. ## Active lifecycle, sourced per BOM quantity No official successor or second-source cross-reference is listed; the TL431 family is broadly second-sourced across multiple manufacturers, but this exact suffix variant should be qualified against the BOM position.","metaTitle":"TL431AICT Shunt Regulator, ±1% Tolerance, SOT-323-6L","metaDescription":"TL431AICT adjustable shunt voltage reference, 100 mA output, ±1% accuracy, -40°C to 105°C, SOT-323-6L surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","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":"700 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~105°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-323-6L","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d3856169bdff63c55d41eeae5a91cadc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431AICT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/TL431AICT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/TL431AICT when reusing this data.
