That half-percent matters when you are setting a 2.495 V reference for an ADC or a 5 V rail supervisor and cannot afford to trim every board. This part is fine for a benchtop power supply, a home appliance control board, or an office router. Do not spec it for a motor drive enclosure or an outdoor telecom cabinet where the ambient hits 85°C — the reference drifts and the cathode current minimum of 600 µA may not hold regulation at temperature extremes. ## SC-70-6 package — tiny but reworkable The SC-70-6 (also known as SOT-363) is a 6-pin surface-mount package about 2 mm × 2.1 mm. No hidden leads under the body — the pins are on the sides, so orientation is obvious once you see the pin-1 mark. If you are swapping this in the field, bring a hot-air station or a really steady hand; the pad pitch is tight.","metaTitle":"TL431BCDCKR Shunt Voltage Reference, ±0.5% Tolerance","metaDescription":"TL431BCDCKR adjustable shunt reference, 2.495 V to 36 V output, ±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":"$0.1539","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431BCDCKR/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of TL431BCDCKR?","answer":"The tolerance is ±0.5%, which is tighter than the standard TL431's ±2% or ±1% grades."},{"question":"What is the cathode current for TL431BCDCKR?","answer":"The minimum cathode current for regulation is 600 µA."},{"question":"Can TL431BCDCKR be used as a replacement for TL431A?","answer":"The TL431BCDCKR is a tighter-tolerance variant of the same TL431 family.
