Procurement Notes
Verify the specific suffix ME3 indicates Pb-free and RoHS compliance status against the latest manufacturer documentation. Confirm the active status and availability through authorized distributors, as component lifecycle stages may change. Ensure the TO-92 package dimensions match your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, high-accuracy shunt regulator is required for voltage referencing. The ±1% tolerance makes it suitable for applications demanding tighter voltage control than standard Zener diodes. Consider the thermal performance and package size constraints associated with the TO-92 housing during design integration.
Part Context
This part belongs to the TL431 family of precision programmable references, widely used as a drop-in replacement for Zener diodes in various analog and digital circuits. The TL431 series is known for its versatility in providing stable reference voltages across a broad range of industrial and consumer electronics applications.
Replacement Considerations
Compatible substitutes include TL431AIDBZR and TL431ACLP, provided they meet the same electrical specifications and package requirements. Verify pinout compatibility and thermal characteristics when transitioning between different manufacturers or package types.
