Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as it may indicate variations in packaging or compliance status. Confirm that the required Zener voltage and power dissipation ratings align with the circuit design specifications before procurement. Ensure the manufacturer source is authorized to guarantee component authenticity and traceability.

Single Zener Diodes Selection Notes

Select this component when a precise 8.5 V reference is needed in a standard axial leaded package. Consider the 500 mW power rating and 100 Ohm impedance limits during thermal and load analysis. Verify compatibility with the intended operating temperature environment and ensure the through-hole footprint matches the PCB layout requirements.

Single Zener Diodes Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology.
