Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as this component has been produced by multiple vendors including Motorola/NXP and Microsemi under similar part numbers. Confirm that the DO-35 package and 500 mW rating match your design requirements. Check for RoHS compliance status if required by your manufacturing standards, noting variations across different production batches and suppliers.

Single Zener Diodes Selection Notes

Select this component when a standard 15 V Zener reference is needed in a compact axial package. Ensure the circuit can handle the 500 mW power dissipation without exceeding thermal limits. Consider the ±5% tolerance for precision requirements and verify that the DO-35 form factor fits the available PCB space and mounting constraints.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of single Zener diodes, widely used for general-purpose voltage regulation.
