Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required tolerance level against official Microchip documentation. Confirm that the DO-204AL package dimensions match your PCB footprint requirements. Ensure the 1.5W power rating accommodates thermal constraints in your final assembly design before procurement.

Single Zener Diodes Selection Notes

Select this component when an 82V regulated reference is needed in a through-hole configuration. The 1.5W power rating supports moderate current loads. Verify that the 160 Ohm impedance meets noise sensitivity requirements. Compare against standard commercial variants if military qualification is not strictly necessary for the target application environment.
