Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout and tolerance variations. Ensure the SOT-89 package matches your PCB footprint requirements. Confirm the operating temperature range aligns with your system's environmental conditions before finalizing procurement.

Selection Notes

Select this component when a compact SOT-89 package is required for space-constrained designs. It is suitable for applications needing precise voltage referencing with moderate current handling capabilities. Consider the 0°C to 70°C operating range when designing for industrial or consumer environments.

Part Context

This part belongs to the TL431 family of precision shunt regulators. It serves as a cost-effective alternative to discrete zener diodes, offering superior accuracy and temperature stability. The TL431 series is widely used in power supply feedback loops and reference voltage generation circuits.

Replacement Considerations

Cross-reference with standard TL431 variants from other manufacturers if sourcing constraints exist. Verify that substitute parts maintain the same SOT-89 package and electrical characteristics to ensure compatibility.
