The device is rated for a power dissipation of 500 mW and operates in the through-hole DO-204AH (DO-35) axial leaded package. This component belongs to the JEDEC registered 1N5221 through 1N5281 series, utilizing internal metallurgical bond construction for reliability.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced structural integrity
• JEDEC registered part within the 1N5221 thru 1N5281 series
• Through-hole axial leaded package configuration

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix /TR against the manufacturer's official datasheet to confirm tape-and-reel packaging requirements. Ensure the DO-204AH package dimensions match the target PCB footprint. Confirm that the 2.7 V nominal voltage and ±5% tolerance align with the circuit design specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a standard 2.7 V Zener voltage is required in an axial glass package. The 500 mW power rating suits low-current regulation tasks. Consider the ±5% tolerance if tighter voltage precision is not critical. Verify compatibility with existing assembly processes for through-hole mounting technologies.

Single Zener Diodes Part Context

This part is part of the widely used 1N52xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options ranging from low voltages up to higher breakdown values. The 1N5223 specifically provides a 2.7 V breakdown, serving as a common reference point in analog signal conditioning and power supply stabilization designs.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5223 equivalents in DO-35 packages. Verify that substitute parts maintain the same 2.7 V nominal voltage, 500 mW power rating, and ±5% tolerance. Ensure mechanical fit and thermal characteristics are compatible with the original design constraints.
