1N5254

Single Zener Diodes Overview

The Microchip Technology 1N5254A is a single Zener diode with a nominal voltage of 27 V and a power dissipation rating of 500 mW. It features a 10% voltage tolerance, a maximum reverse leakage current of 100 nA, and a Zener impedance of 41 Ohms at a test current of 4.6 mA. The device operates within a temperature range of -65°C to +200°C and utilizes a DO-7 glass axial-lead package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation in the 27 V range for circuit protection and reference applications
• Constructed with a hermetically sealed glass axial-lead package for environmental durability
• Designed for through-hole mounting on printed circuit boards

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Overvoltage protection components
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific suffix against official datasheets, as variations like 'A' or 'B' indicate different voltage tolerances. Confirm package type and screening levels match design requirements. Cross-reference manufacturer part numbers to ensure compatibility with existing supply chains and avoid counterfeit components.

Single Zener Diodes Selection Notes

Select based on required voltage tolerance and operating temperature range. Ensure the 500 mW power rating suits the thermal environment. Verify package dimensions for PCB layout compatibility. Consider tighter tolerance variants if precision is critical.

Single Zener Diodes Part Context

This component belongs to the popular 1N5221 through 1N5281 series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection from 2.4 to 200 volts in standard 5% or 10% tolerances. These glass axial-leaded DO-7 Zeners are widely used in general-purpose electronics.
