Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets, as variations exist between standard and taped/reel formats. Confirm current availability status directly with the manufacturer or authorized distributors due to potential restricted supply conditions associated with military-grade components. Ensure compliance with relevant export control regulations when procuring this item.

Single Zener Diodes Selection Notes

Select this component for designs requiring robust voltage reference stability in extreme conditions. The 1.5W power rating supports moderate current handling in compact layouts. Consider thermal management requirements given the glass package characteristics. Validate that the 180V breakdown voltage aligns precisely with circuit protection thresholds without exceeding maximum ratings.

Single Zener Diodes Part Context

This part belongs to the 1N44xx series of surface-mount Zener diodes offered by Microsemi. These devices are engineered to replace traditional axial-leaded counterparts in modern PCB layouts while maintaining military-grade performance levels. The series provides various voltage options within a standardized small outline package format.

Single Zener Diodes Replacement Considerations

Direct substitutes may include other JANTX-qualified 180V Zener diodes from Microsemi or equivalent military-grade alternatives from other manufacturers meeting MIL-PRF-19500/406 specifications. Verify pinout compatibility and physical dimensions before substitution.
