Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. Confirm that the component meets all required environmental and screening standards before integration into final designs.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener reference is required in a compact surface-mount form factor. Ensure the application environment supports the specified wide operating temperature range and thermal dissipation requirements.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface-mountable glass Zener diodes. It serves as the SMD equivalent to the JEDEC registered 1N3016 through 1N3051 axial lead devices, offering higher power ratings in a smaller footprint.

Single Zener Diodes Replacement Considerations

Equivalent axial lead parts include the 1N3044B. For screened variants, prefixes such as MQ, MX, or MV may be used to denote JAN, JANTX, or JANTXV equivalents.
