It is part of the Automotive, AEC-Q100 series, qualified for use in under-hood and cabin electronics where temperature swings from -40°C to 125°C are routine. The shunt topology means it behaves like a Zener diode — no separate supply pin, just a cathode and anode — which simplifies PCB layout and keeps the BOM count low. Typical applications include ADC references in engine control units, sensor bias for exhaust gas or pressure transducers, and comparator thresholds in battery management systems. ## What the ratings mean for your BOM Output current is rated at 15 mA. Minimum cathode current is 78 µA. ## SOT-23-3 package — field-fit and footprint The part comes in a standard SOT-23-3 (TO-236-3 / SC-59) surface-mount package. Three pins — cathode, anode, and no-connect.","metaTitle":"LM4050QCEM3-4.1/NOPB Shunt Reference, ±0.5%, AEC-Q100","metaDescription":"TI LM4050QCEM3-4.1/NOPB precision 4.096V shunt reference, ±0.5% tolerance, 78 µA cathode current, -40°C to 125°C.
