It delivers a programmable output from 2.5 V up to 36 V with a tight ±0.4% initial tolerance, and can sink up to 100 mA. The -55°C to 125°C operating range qualifies it for military, avionics, and downhole instrumentation where the board sees wide thermal swings. The shunt topology means it behaves as a three-terminal programmable Zener — no external pass transistor needed for moderate loads, just a single resistor from the supply rail. ## Lifecycle and sourcing posture The TL1431MDREP carries an active product status and is ROHS3 compliant. The 8-SOIC package is a common footprint, so it cross-references to many standard shunt references if a second source is needed — but the military temperature range and ±0.4% tolerance make this the tighter-spec option for harsh-environment designs.","metaTitle":"TL1431MDREP Shunt Voltage Reference, Adjustable, ±0.4%","metaDescription":"TL1431MDREP adjustable shunt voltage reference, ±0.4% tolerance, 100 mA output, -55°C to 125°C, 8-SOIC.

For a pin-compatible shunt replacement, look at the TL431 family in the same 8-SOIC package; the TL1431 offers the wider -55°C to 125°C range versus the TL431's typical -40°C to 85°C."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL1431MDREP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL1431MDREP when reusing this data.
