Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and specific packaging configuration. Confirm that the SOT-23-3 footprint matches the target PCB design. Ensure thermal management requirements align with the specified operating temperature range during integration.

Selection Notes

Select this component when an adjustable shunt regulator is required within the 2.5 V to 36 V range. Consider the 1% initial accuracy and 92 PPM/C temperature coefficient for precision needs. Verify compatibility with the SOT-23-3 package constraints and ensure the application falls within the -40°C to +125°C operational limits.

Part Context

This device belongs to the TL432 family of precision programmable references from Texas Instruments. It shares the SOT-23-3 form factor with other components in the series but offers distinct electrical characteristics compared to fixed-voltage references or different accuracy grades within the same package type.

Replacement Considerations

Publicly confirmed substitute part numbers include TL431IDBZT and TL431IDBZR.
