Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' indicates the 1% tolerance variant when ordering. Confirm that the component meets the required MIL-PRF-19500/435 qualification level for your application. Ensure compatibility with the DO-35 axial lead form factor during PCB layout. Check for RoHS compliance status if applicable to commercial variants.

Single Zener Diodes Selection Notes

Select this component for applications requiring precise voltage regulation under wide thermal variations. The 1% tolerance ensures stability where standard 5% parts are insufficient. Consider the low dynamic impedance for maintaining regulation accuracy under varying load currents. Verify power derating requirements based on ambient operating temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener diodes. These devices are designed for rugged environments and offer extensive voltage selection from 1.8 V to 100 V. The series supports multiple reliability levels including JAN, JANTX, JANTXV, and JANS.

Single Zener Diodes Replacement Considerations
