Single Zener Diodes Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm that the ordering suffix matches the required packaging format, as the standard designation implies specific reel quantities. Ensure compliance with project requirements regarding halogen content and flammability ratings before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 39V reference is required in high-temperature environments due to its extended thermal rating. The DO-41 package suits applications needing robust axial leads. Verify that the 1.5W power dissipation capacity meets the circuit's thermal design limits under derating conditions.
