Cathode current rating is 100 mA, with a minimum operating current of 600 µA. ## ±1% tolerance — the precision tier for this shunt reference The ±1% tolerance on the TL431ACDT puts it in the precision band of the TL431 family. For a 2.5 V reference, that means the output sits within 25 mV of nominal at 25°C before any temperature drift. That's tight enough for most 8-bit and 12-bit ADC references, error-amplifier setpoints, and comparator thresholds. No last-time-buy notice, no end-of-life announcement. The ROHS3 compliance is current.","metaTitle":"TL431ACDT adjustable shunt voltage reference, ±1%, 8-SOIC","metaDescription":"STMicroelectronics TL431ACDT adjustable shunt voltage reference, ±1% tolerance, 2.495 V to 36 V output, 100 mA cathode current, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"8-SOIC (0.154\\\", 3.90mm Width)","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":"8-SOIC","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6400","priceTiers":[{"qty":1,"price":"$0.64000","currency":"USD"},{"qty":10,"price":"$0.56700","currency":"USD"},{"qty":25,"price":"$0.53240","currency":"USD"},{"qty":100,"price":"$0.43450","currency":"USD"},{"qty":250,"price":"$0.40356","currency":"USD"},{"qty":500,"price":"$0.34344","currency":"USD"},{"qty":1000,"price":"$0.28350","currency":"USD"},{"qty":2500,"price":"$0.28350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d3856169bdff63c55d41eeae5a91cadc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431ACDT/alternatives.json"},"ai":{"faq":[{"question":"Is TL431ACDT compatible with TL431A socket?","answer":"Yes, the TL431ACDT is pin-compatible with any standard TL431A in an SOIC-8 footprint.
