Single Zener Diodes Procurement Notes

Verify the specific suffix CUS against the official Microchip datasheet to confirm exact mechanical and environmental qualifications. Ensure the order specifies the correct packaging format, as standard distribution may vary from bulk or tape-and-reel options. Confirm that the supplier provides traceability documentation required for defense contracts. Check for any recent Product Change Notifications (PCNs) affecting the manufacturing site or materials. Validate compliance with relevant export control classifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V Zener reference is needed in a through-hole configuration. The 1.5 W power rating supports moderate current loads without excessive heat sinking. The MIL-PRF-19500/435 qualification makes it suitable for harsh environments where commercial parts would fail. Consider the 7 ohm impedance for noise-sensitive applications. Ensure the PCB layout accommodates the DO-41 package dimensions and lead spacing.
