1N5223

Single Zener Diodes Overview

The Microchip Technology 1N5223 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 2.7 V with a standard tolerance of 5%. The device operates in the DO-35 (DO-204AH) axial leaded glass package, suitable for through-hole mounting. It supports a maximum power dissipation of 500 mW and maintains functionality across an extended temperature range from -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 75 µA at 1 V and a Zener impedance of 30 Ohms.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a 2.7 V Zener reference.
• Constructed with a hermetically sealed glass axial-lead package for durability.
• Capable of operating reliably in extreme environmental temperatures up to 200°C.

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and lead condition prior to installation. Ensure compliance with project-specific material requirements, noting that this specific part may not meet RoHS directives depending on the manufacturing lot. Validate supplier documentation for traceability.

Single Zener Diodes Selection Notes

Select this component when a precise 2.7 V regulation point is required within a through-hole design. The DO-35 package offers a compact footprint for standard PCB layouts. Consider the 5% tolerance and thermal performance limits during circuit design to ensure stability under varying load conditions and ambient temperatures.

Single Zener Diodes Part Context

This component belongs to the widely recognized 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series provides a broad selection of voltages ranging from 2.4 V to 200 V in standard tolerances. These devices are established industry standards for general-purpose voltage regulation in discrete semiconductor applications.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5223B for tighter tolerance requirements or the 1N5223C for precision applications. Surface-mount equivalents such as the CDLL5223A offer similar electrical characteristics in a different package format.
