The ±2.2% tolerance on the reference voltage determines how tightly the output can be held across temperature and load — for a 5 V rail built with this device, the set-point uncertainty is roughly ±110 mV before resistor tolerances are added. ## Temperature range and environment — industrial and automotive-grade operation The wide temperature range means the reference holds its accuracy across the thermal cycle of a production run — no cold-start drift or high-side sag that would shift the regulation point of a downstream converter. ## Package and footprint — what the SC-70-6 means for assembly The SC-70-6 (also known as 6-TSSOP or SOT-363) is a 6-lead surface-mount package with a 0.65 mm lead pitch. It is small enough for handheld and portable designs but still hand-solderable under a microscope. The tape-and-reel delivery (3,000 pieces per reel) feeds directly into a pick-and-place machine — no tube handling. Check the MSL before reflow; the SC-70-6 body is thin and can popcorn if the moisture barrier is exceeded. For volume production, the BOM line is stable — no forced redesign cycle from an unexpected EOL.","metaTitle":"TL431QDCKTG4 Adjustable Shunt Reference, ±2.2%, SC-70-6","metaDescription":"Texas Instruments TL431QDCKTG4 adjustable shunt voltage reference. 2.495 V min output, 36 V max, 100 mA cathode current, ±2.2% tolerance.","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":"±2.2%","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":"1 mA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431QDCKTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the TL431QDCKTG4 tolerance?","answer":"The reference voltage tolerance is ±2.2% at 25°C.
