Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet identifies Microsemi while other sources list Microchip Technology. Confirm compliance with MIL-PRF-19500/356 requirements if military qualification is mandatory. Ensure the axial lead finish matches design specifications, noting potential variations between tin/lead and solid silver terminations in previous inventory batches.

Single Zener Diodes Selection Notes

Select this component when a robust 5-watt Zener regulator is required for harsh environments. The wide operating temperature range supports extreme thermal conditions. Verify that the 24 V nominal voltage aligns with circuit requirements. Consider surface-mount equivalents like the 1N4967US if board space constraints necessitate a MELF package instead of axial leads.
