1N5262B-T50A

Single Zener Diodes Overview

The Fairchild Semiconductor 1N5262B-T50A is a single silicon Zener diode designed for through-hole mounting in the DO-35 (DO-204AH) axial leaded package. It features a nominal Zener voltage of 51 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device operates within a temperature range of -65 °C to +200 °C, with a test current of 2.5 mA and a maximum reverse leakage current of 100 nA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via unidirectional Zener breakdown characteristics
• Constructed from silicon material for reliable semiconductor performance
• Designed for through-hole installation using standard axial lead configuration

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify manufacturer origin as Fairchild Semiconductor or successor entities like onsemi due to corporate acquisitions. Confirm package style matches DO-35 specifications and check RoHS compliance status against specific production batches. Ensure testing conditions align with standard datasheet parameters for accurate electrical validation.

Single Zener Diodes Selection Notes

Select this component when a 51 V regulation point is required with moderate power handling capabilities. The DO-35 package suits prototyping and low-volume manufacturing where through-hole assembly is preferred. Consider thermal management requirements given the 500 mW rating and operating temperature limits up to 200 °C.

Single Zener Diodes Part Context

This part belongs to the 1N52xxB series of Zener diodes, widely used in discrete semiconductor applications. Fairchild Semiconductor was a major producer before its acquisition by onsemi. The 1N5262B designation specifically identifies the 51 V variant within this standardized numbering system for axial glass-passivated junction diodes.

Single Zener Diodes Replacement Considerations

Equivalent parts include Vishay 1N5262B-TR and Diodes Inc. 1N5262B-B. Verify pinout compatibility and ensure replacement devices meet the same 51 V Zener voltage and 500 mW power dissipation ratings for direct substitution.
