• Features hermetically sealed glass axial-lead construction for durability
• Offers minimal capacitance characteristics suitable for high-frequency applications

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection systems
• Clipper and clamper circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging per EIA-296 standards. Confirm that the 'B' suffix denotes the required ±5% voltage tolerance. Ensure compatibility with the DO-35 package dimensions and lead configuration before integration into the assembly process.

Single Zener Diodes Selection Notes

Select this component when a precise 4.3 V regulation point is required with tight tolerance constraints. Consider the low thermal resistance and wide operating temperature range for environments subject to significant heat variations or extreme cold conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series provides a comprehensive selection of voltages from 2.4 V to 200 V, utilizing standard JEDEC registration for interchangeability and reliability in general-purpose electronic designs.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5229B devices in the DO-35 package. Surface mount equivalents are available in the MLL5229B MELF style package for automated assembly requirements.
