Single Zener Diodes Procurement Notes

Verify that the specific order includes the SM suffix designation to confirm the axial glass package variant. Confirm compliance with required space levels (TX, TXV, or Level 7) during procurement. Ensure the requested tolerance matches the 1% specification for critical circuit accuracy. Validate that the manufacturer documentation explicitly lists SSDI or Microchip as the source for this specific hermetic part number.

Single Zener Diodes Selection Notes

Select this component when hermetic sealing is mandatory for long-term reliability in vacuum or corrosive environments. The 3W power rating allows for robust performance in high-voltage regulation tasks. The wide temperature range supports operation in uncontrolled external conditions. Verify that the 6.8V breakdown voltage aligns precisely with the circuit design requirements before integration.

Single Zener Diodes Part Context

This component belongs to the SZN5063 series, which encompasses various Zener diodes ranging from 6.8V to 400V. The series is characterized by its hermetic glass construction and high-power handling capabilities. It serves as a direct replacement for standard non-hermetic 1N5063 through 5117 series diodes where environmental sealing is critical.

Single Zener Diodes Replacement Considerations

Directly replaces standard 1N5063 diodes in designs requiring hermetic sealing. Ensure substitute parts maintain the same 3W power rating and 1% tolerance. Verify that any alternative offers equivalent thermal resistance and maximum operating temperature specifications.
