Minimum cathode current is 700 µA, which sets the lower bound for the bias resistor in a typical series-resistor configuration. The 100 mA output rating defines the maximum load the shunt can sink while maintaining regulation. For BOM planning, this part presents no near-term obsolescence risk.","metaTitle":"TL431AIPG4 Shunt Reference, ±1% Tolerance, 8-PDIP","metaDescription":"Texas Instruments TL431AIPG4 adjustable shunt voltage reference, ±1% tolerance, 100 mA output, 2.495 V to 36 V range, -40°C to 85°C, 8-PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","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-PDIP","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/TL431AIPG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431AIPG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431AIPG4 when reusing this data.
