Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging configuration. Confirm MIL-PRF-19500/406 compliance status directly with manufacturer documentation. Ensure compatibility with SQ-MELF (D-5A) footprint requirements during integration planning.

Single Zener Diodes Selection Notes

Select this component when military qualification and hermetic sealing are mandatory. The 36 V rating suits specific reference voltage needs. Consider the 1.5 W power limit and thermal management requirements for the SQ-MELF package in the final design.

Single Zener Diodes Part Context

This part belongs to the 1N4478 series of 1.5 W Zener diodes. It represents the JANTXV quality level, offering tighter specifications than standard JAN or JANTX variants. The series provides industry-standard voltage options in a robust glass-encapsulated form factor.

Single Zener Diodes Replacement Considerations

JAN1N4478DUS/TR and JANTX1N4478DUS/TR offer equivalent electrical parameters with lower qualification levels.
