Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required ±2% tolerance level against standard ±5% variants. Confirm the '-TR' designation matches the reel packaging requirements for automated assembly processes. Ensure the DO-35 lead spacing aligns with the target PCB footprint design specifications.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation within tight tolerances is critical. The DO-35 package offers a balance between power handling and compact size. Consider the thermal resistance characteristics if operating near the maximum power dissipation limits in enclosed environments.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal voltages from 2.4 V to 75 V, providing standardized options for various circuit design needs across consumer and industrial electronics applications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes rated at 18 V with ±2% tolerance. Verify that alternative parts meet the same 500 mW power dissipation and 175 °C junction temperature ratings.
