Single Zener Diodes Procurement Notes

Verify the specific suffix against official datasheets, as variations exist within the family. Confirm RoHS compliance status and packaging type (bulk or tray) prior to ordering. Ensure the required Zener impedance and leakage current specifications align with the design requirements for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a precise 3 V reference is needed in a standard axial leaded package. Consider the 5% voltage tolerance and 1600 ohm impedance for circuit stability. Evaluate the thermal derating characteristics if operating near the maximum power dissipation limit of 500 mW.
