1N5274

Single Zener Diodes Overview

The Microchip Technology 1N5274 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 130V with a tolerance of 20%. The device has a power dissipation rating of 0.417W and utilizes a DO-204AA (DO-7) glass axial-lead package. It is hermetically sealed and configured as a single unidirectional component.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction
• Silicon Zener voltage regulation capability
• Single unidirectional configuration

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as historical data indicates production by Microsemi, now part of Microchip Technology. Confirm compliance status, as some records indicate leaded construction which may not meet RoHS standards. Ensure the package type matches the required DO-7 or DO-204AA specification for your design.

Single Zener Diodes Selection Notes

Select this component when a 130V Zener reference is required in an axial-lead package. Note that the 20% tolerance is relatively wide; consider suffix variants like 'A' or 'B' if tighter tolerances such as 5% or 10% are necessary for precision applications.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of 0.5W Zener diodes. While rated for up to 0.5W, the 1N5274 specifically lists a 0.417W dissipation in official databases. It serves as a high-voltage option within the series, covering the range from 2.4V to 200V.
