Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm tolerance class, as standard commercial variants may differ. Ensure the source document explicitly lists the 1N4480C part number within the MIL-PRF-19500/406 qualification scope. Confirm package type matches the SQ SMT specification found in related series data.

Single Zener Diodes Selection Notes

Select this component for applications requiring hermetic sealing and surface mount form factors. Verify that the 43V breakdown voltage aligns with circuit requirements. Consider the 40 ohm dynamic impedance for noise-sensitive designs. Ensure compatibility with MIL-PRF-19500/406 standards if military qualification is mandatory.

Single Zener Diodes Part Context

This device is part of the 1N4460US through 1N4496US series of 1.5-watt Zener diodes. These components are designed as surface mount equivalents to popular JEDEC registered axial leaded series. The series offers various voltage selections from 3.3 to 200 volts with standard 5% tolerance options.

Single Zener Diodes Replacement Considerations

Check for JANTX or JAN prefixes for equivalent military grades. Verify 1N4480US/TR for tape and reel packaging options. Ensure any substitute maintains the SQ SMT package and hermetic seal specifications.
