The shunt topology means it sinks current through the cathode to regulate the output voltage – a workhorse for linear regulators, isolated flyback feedback loops, and comparator-based threshold detectors where a precision reference isn't required. ## Active lifecycle – no last-time-buy worry No EOL notice, no last-time-buy deadline to track. For procurement planning, this means no allocation scramble and no forced redesign for the foreseeable future. ## Commercial temperature range – indoor use only That covers office equipment, consumer electronics, and indoor power supplies. It is not specified for indus. ## 8-SOIC footprint – board layout fit It fits automated pick-and-place assembly and reflow soldering. Tape & Reel and Cut Tape options are available for volume or prototype quantities.","metaTitle":"STMicroelectronics TL431CDT Shunt Voltage Reference, 2.495 V","metaDescription":"STMicroelectronics TL431CDT adjustable shunt voltage reference. 2.495 V min, 36 V max, 100 mA output, ±2.21% tolerance. 8-SOIC surface mount, 0°C to 70°C.","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":"±2.21%","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":"1 mA","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":"$0.4200","priceTiers":[{"qty":1,"price":"$0.42000","currency":"USD"},{"qty":10,"price":"$0.35800","currency":"USD"},{"qty":25,"price":"$0.33400","currency":"USD"},{"qty":100,"price":"$0.26720","currency":"USD"},{"qty":250,"price":"$0.24816","currency":"USD"},{"qty":500,"price":"$0.20998","currency":"USD"},{"qty":1000,"price":"$0.16226","currency":"USD"},{"qty":2500,"price":"$0.14794","currency":"USD"},{"qty":5000,"price":"$0.13840","currency":"USD"},{"qty":12500,"price":"$0.12885","currency":"USD"},{"qty":25000,"price":"$0.12217","currency":"USD"},{"qty":62500,"price":"$0.11931","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d3856169bdff63c55d41eeae5a91cadc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431CDT/alternatives.json"},"ai":{"faq":[{"question":"What is the equivalent or replacement for TL431CDT?","answer":"For a tighter tolerance, the STMicroelectronics TL1431ACL5T offers ±0.25% tolerance with a 90 ppm/°C temperature coefficient, also in an adjustable shunt topology and surface-mount package.
