The 15 mA cathode current rating handles the shunt path for typical low-power loads, and the 100 µA minimum cathode current keeps it biased cleanly even in micropower designs. ## Industrial temp range and package fit The SOT-23-5 package is a standard footprint; the SC-74A / SOT-753 case is the same 5-pin outline. Surface-mount rework is straightforward with hot air or a fine-tip iron — no lab bench needed, it swaps on site if you have the kit. ## Active lifecycle — no end-of-life watch For a production BOM this means you are not chasing a sunset part; it is a stable line-item for ongoing builds.","metaTitle":"TLV431BQDBVRE4 shunt voltage reference, ±0.5% tolerance","metaDescription":"Texas Instruments TLV431BQDBVRE4 adjustable shunt voltage reference, ±0.5% tolerance, 15 mA output, -40°C to 125°C, SOT-23-5.","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":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"100 µA","Base Product Number":"TLV431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"6 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431BQDBVRE4/alternatives.json"},"ai":{"faq":[{"question":"Is TLV431BQDBVRE4 a drop-in replacement for TL431?","answer":"The TLV431BQDBVRE4 is a lower-voltage variant of the TL431 family — it shares the same shunt-reference topology and SOT-23-5 footprint, but its output range tops out at 6 V versus the TL431's 36 V.
