Procurement Notes

This component is officially discontinued and marked as obsolete by the manufacturer. Availability is restricted to existing stock or secondary market channels. Verify end-of-life status and lead times carefully before design finalization. Ensure compatibility with alternative sources if sourcing from non-direct distributors.

Selection Notes

Select this part for applications requiring high accuracy in small form factors. The SOT-23-5 package suits space-constrained designs. Consider the limited operating temperature range and lack of shutdown functionality when evaluating thermal and power constraints. Verify that the 100 mA maximum cathode current meets load requirements.

Part Context

Part of the SC431LC5SK series, this component belongs to Semtech's portfolio of power management integrated circuits. It serves as a two-terminal voltage reference, functioning similarly to Zener diodes but with superior stability and adjustability. The series targets general-purpose voltage regulation needs in consumer and industrial electronics.
