Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance when sourcing. Confirm the package type matches the design requirements as it differs from through-hole variants. Ensure the manufacturer source is Microchip or an authorized distributor to guarantee authenticity and traceability for critical applications.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with high-temperature capability is required. The 20 V rating suits specific reference needs. Compare against standard axial packages if board space allows, but choose this SMD version for automated assembly and compact layouts requiring robust thermal performance.

Single Zener Diodes Part Context

This part belongs to the 1N4114 series of Zener voltage regulators produced by Microchip Technology. It is a surface-mount variant of the traditional 1N4114, offering similar electrical specifications in a modern package format suitable for automated PCB assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N4114UR-1 for hermetic surface-mount applications. For non-hermetic options, verify compatibility with other 20V 0.5W SMB Zener diodes from compatible manufacturers.
