Single Zener Diodes Procurement Notes

Verify the specific ordering suffix TAP corresponds to the Ammopack packaging configuration as defined in the manufacturer's order instructions. Confirm that the A-series designation aligns with the required ±1% tolerance specification for your design. Ensure the component meets all applicable environmental compliance standards relevant to your region before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a tighter voltage tolerance than the standard C-series is required. The BZX55A variant offers ±1% accuracy suitable for precision applications. Consider the DO-35 through-hole package constraints and the 500 mW power dissipation limit relative to ambient temperature conditions. Verify thermal resistance requirements against the lead length specifications provided in the datasheet.

Single Zener Diodes Part Context

This part belongs to the BZX55 series of silicon epitaxial planar Zener diodes manufactured by Vishay Semiconductors. The series utilizes a standard glass case (DO-35) and is designed for general-purpose voltage regulation. The 'A' suffix indicates a tighter manufacturing tolerance compared to the standard 'C' grade, while the 'TAP' suffix denotes the specific Ammopack packaging format.
