1N5261

Single Zener Diodes Overview

The 1N5261 is a silicon planar Zener diode manufactured by SMC Diode Solutions. It features a nominal Zener voltage of 47 V with a power dissipation rating of 0.5 W (500 mW). The device utilizes a DO-35 glass axial leaded package and offers standard voltage tolerance options, typically ±5% or ±10%. Designed for unidirectional voltage regulation, it operates within a junction temperature range suitable for general electronic applications.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Constructed using silicon planar technology for reliability
• Hermetically sealed in a DO-35 glass axial package

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix code to confirm exact voltage tolerance and manufacturer lot details. Confirm RoHS compliance status as requirements vary by production era. Check for obsolete status indicators, as availability may be limited. Ensure the DO-35 package dimensions match the target PCB footprint before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a 47 V regulation point is required in an axial through-hole configuration. Consider the 0.5 W power rating against expected thermal loads. Evaluate tolerance requirements, as tighter specifications may necessitate alternative suffixes. Verify that the glass package material meets environmental constraints for the intended deployment environment.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N52xx series of Zener diodes, covering voltages from 2.4 V to 200 V. The 1N5261 specifically targets the 47 V segment. Similar devices are produced by various manufacturers including Microsemi, NXP, and EIC, often sharing identical electrical characteristics but differing in packaging or sourcing history.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N5261B from Central Semiconductor Corp. Other compatible alternatives include parts from Vishay, NXP, and Microsemi offering equivalent 47 V, 0.5 W specifications in DO-35 or surface mount packages like DO-213AA.
