1N5260B

Single Zener Diodes Overview

The onsemi 1N5260B is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 43 V with a tolerance of 5%. The device is housed in a DO-35 glass axial-lead package and supports through-hole mounting. It has a maximum power dissipation of 500 mW at 25°C, with derating required above this temperature. The component operates within a junction temperature range of -65°C to +175°C and exhibits a typical reverse leakage current of 100 nA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection

• Overvoltage protection
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation as the 1N5260B part number is produced by multiple vendors including Microchip Technology, Rectron, and NXP Semiconductors. Confirm that the selected unit matches the required electrical tolerances and package specifications. Ensure compliance with RoHS directives if lead-free composition is mandatory for the assembly process.

Single Zener Diodes Selection Notes

Select this component when a precise 43 V regulation point is required in low-power circuits. The 500 mW rating suits applications with minimal heat generation. Consider the DO-35 package dimensions for PCB layout constraints. Evaluate the 5% voltage tolerance against circuit sensitivity requirements before finalizing the design.

Single Zener Diodes Part Context

This device belongs to the standard 1N52xx series of Zener diodes, widely used for general-purpose voltage regulation. The series offers various voltage options within the same physical footprint, allowing for flexible design choices. The 1N5260B specifically addresses the need for stable 43 V references in industrial and consumer electronics.

Single Zener Diodes Replacement Considerations

Equivalent parts include the Microchip Technology 1N5260B/TR and the Rectron 1N5260B-B. Verify pinout compatibility and ensure the substitute meets the same 43 V nominal voltage and 500 mW power dissipation ratings.
