Single Zener Diodes Procurement Notes

Verify RoHS compliance status as some listings indicate non-compliance. Confirm package type DO-204AH availability. Check manufacturer datasheet for specific impedance test conditions. Ensure lead-free status matches project requirements. Validate supplier authenticity for Microchip Technology components.

Single Zener Diodes Selection Notes

Select this component when a stable 19.2 V reference is required with minimal temperature drift. The low noise characteristic makes it suitable for sensitive analog applications. Consider the axial DO-35 package for through-hole mounting constraints. Verify that the ±5% tolerance meets circuit accuracy specifications.

Single Zener Diodes Part Context

This part belongs to Microchip's family of single Zener diodes. It is historically associated with Microsemi Corporation before acquisition. The DO-7 designation refers to the physical package style. It serves as a specialized reference element rather than a standard rectifier or protection diode.

Single Zener Diodes Replacement Considerations

Check for equivalent temperature compensated Zener diodes with 19.2 V nominal voltage. Verify pinout compatibility for DO-35 packages. Ensure noise specifications and impedance characteristics match original design requirements.
