LM4040B30QFTA

Overview

The LM4040B30QFTA is an automotive-compliant precision micropower shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed 3.0V output with a tight initial tolerance of ±0.2% at +25°C. The device operates within a wide current range from 60µA to 15mA and maintains stability across an extended temperature range of -40°C to +125°C. It features a maximum temperature coefficient of 100 ppm/°C and low output noise, housed in a compact SOT23 surface-mount package.

Feature Summary

Automotive compliant with AEC-Q100 qualification and PPAP capability for specific change control requirements
High precision bandgap circuit offering stable reference voltage over industrial temperature ranges
Capable of driving capacitive loads without requiring external output capacitors for stability

Applications

Automotive reference voltages
Automotive data acquisition systems

Procurement Notes

Verify the component matches the exact automotive grade designation (LM4040B30Q) and packaging suffix (FTA). Confirm compliance with RoHS directives and lead-free specifications as documented in the manufacturer's quality definitions. Ensure the ordering quantity aligns with the standard tape and reel packing configuration provided in the official datasheet.

Selection Notes

Select this part when high accuracy is required alongside strict automotive reliability standards. The B-grade tolerance ensures minimal deviation at room temperature. Verify that the operating current remains within the specified 60µA to 15mA window to maintain optimal performance and stability characteristics defined in the electrical specifications.

Part Context

This component belongs to the LM4040Q family of micropower shunt references designed specifically for automotive environments. It serves as a pin-for-pin compatible alternative to industry-standard commercial versions while meeting IATF 16949 manufacturing facility requirements. The Q-series designation indicates specialized automotive qualification protocols.
