1N5226BTR

Single Zener Diodes Overview

The 1N5226BTR is a unidirectional silicon Zener voltage regulator diode manufactured by Fairchild Semiconductor. It features a nominal Zener voltage of 3.3 V with a maximum power dissipation of 0.5 W (500 mW). The device utilizes a DO-35 axial leaded package and offers a standard voltage tolerance of ±5%. Designed for through-hole mounting, it operates within a temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 3.3 V level
• Constructed using silicon planar technology for reliability
• Encapsulated in a glass axial-lead DO-35 package

Single Zener Diodes Applications

• General purpose voltage regulation circuits
• Reference voltage sources in electronic systems
• Overvoltage protection applications

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing this component, as Fairchild Semiconductor has undergone corporate restructuring and integration into ON Semiconductor. Confirm that the part number suffix corresponds to the reel packaging format required for your assembly process. Ensure compliance with current RoHS directives and check for any updated ordering codes resulting from system migrations.

Single Zener Diodes Selection Notes

Select this component for low-voltage regulation tasks requiring a 3.3 V reference point. The 0.5 W power rating suits moderate current applications within the DO-35 thermal constraints. Consider the ±5% tolerance for precision requirements and verify that the axial lead form factor aligns with the printed circuit board layout and mounting orientation specifications.

Single Zener Diodes Part Context

This device belongs to the widely utilized 1N52xx series of Zener diodes, which covers a broad spectrum of voltage ratings from approximately 2.4 V to higher values. The 'B' suffix typically denotes a 5% voltage tolerance, distinguishing it from looser tolerance variants. The 'TR' suffix indicates the component is supplied in a tape and reel configuration, facilitating automated surface or through-hole placement machinery.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5226B for bulk packaging or generic equivalents from other manufacturers such as Microsemi or onsemi, provided they match the 3.3 V Zener voltage, 0.5 W power dissipation, and DO-35 package dimensions.
