Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required 2% tolerance level, as other suffixes may denote different tolerances or packaging. Confirm that the MIL-PRF-19500/533 qualification status meets your project's compliance requirements. Ensure the DO-204AH package dimensions are compatible with your PCB layout constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 20V reference is needed in harsh environments. The 500mW power rating suits low-current regulation tasks. Consider the extended temperature range if operating conditions exceed standard commercial limits. Verify that the hermetic seal requirement aligns with the system's environmental exposure specifications.

Single Zener Diodes Part Context

This part belongs to the 1N6309 through 1N6355 series of Zener voltage regulators. These devices are industry-standard components known for their robustness. The JAN prefix specifically denotes military-grade screening and qualification, distinguishing it from commercial variants like the 1N6331C.
