The 100 mA cathode current rating defines the load-driving ceiling; in a shunt configuration the total current through the device (load plus bias) must stay under this limit across the operating temperature range. The 'IDRE4' suffix denotes the tape-and-reel shipping medium — 2,500 units per reel — which is the standard for automated pick-and-place assembly. No LTB window or last-time-buy deadline applies. For dual-sourcing or alternate package options, the base number TL431 covers multiple tolerance grades and package variants (SOT-23, TO-92, SOIC-8) across the same process technology — the 'IDRE4' suffix locks in the ±2.2% grade and the tape-and-reel SOIC-8 format.","metaTitle":"TL431IDRE4 Shunt Regulator, Adjustable, 2.495V Ref, ±2.2%","metaDescription":"Texas Instruments TL431IDRE4 adjustable shunt regulator. 2.495V min output, ±2.2% tolerance, 100 mA cathode current, 8-SOIC.","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":"8-SOIC (0.154\\\", 3.90mm Width)","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~85°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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431IDRE4/alternatives.json"},"ai":{"faq":[{"question":"What package does TL431IDRE4 come in?","answer":"The supplier device package is 8-SOIC."},{"question":"Is TL431IDRE4 RoHS compliant?","answer":"The TL431IDRE4 is a lead-free (RoHS) device as standard from Texas Instruments for this suffix.
