The device operates as a shunt regulator, sinking current through the cathode to regulate the output voltage set by two external resistors. Output can be programmed up to 36 V, and the 100 mA cathode current capability covers most low-to-moderate power regulation tasks without an external pass transistor. ## Package and thermal fit Housed in an SC-70-6 (SOT-363) package, the TL431AIDCKTG4 occupies roughly half the board area of an SOT-23-3. The 6-pin footprint includes separate cathode, reference, and anode connections plus an NC pin for creepage clearance. For extended temperature or automotive use, the A-grade variant (TL431AIDCKTG4) is not AEC-Q100 listed; check the Q1 suffix if under-hood qualification is required. The base product number TL431 spans multiple package and tolerance grades. The AIDCKTG4 suffix denotes the ±1% tolerance grade in a tape-and-reel SC-70-6 package.","metaTitle":"TL431AIDCKTG4 Shunt Voltage Reference, ±1% Tolerance","metaDescription":"Texas Instruments TL431AIDCKTG4 adjustable shunt voltage reference, 2.495V min output, ±1% 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)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","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~85°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":"$0.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431AIDCKTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the accuracy and temperature drift of TL431AIDCKTG4?","answer":"The TL431AIDCKTG4 offers ±1% initial tolerance on the 2.495 V reference.
