1N5259B BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5259B BK TIN/LEAD is a single silicon Zener diode designed for through-hole mounting in DO-35-2 packages. It features a nominal Zener voltage of 9.1 V with a 5% tolerance, dissipating up to 500 mW. The device operates within a temperature range of -65°C to +200°C and exhibits a maximum reverse leakage current of 3 µA at a test current of 20 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single silicon junction structure
• Capable of operating reliably across an extended industrial temperature range
• Utilizes a glass-encapsulated axial leaded package for secure board mounting

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm material composition and compliance status. Ensure the ordering code matches the required voltage tolerance and power dissipation ratings for your design. Confirm availability directly with authorized distributors as supply conditions may vary.

Single Zener Diodes Selection Notes

Select this component when a standard 9.1 V reference is needed in a compact axial package. Evaluate the thermal environment to ensure the 500 mW rating remains sufficient under worst-case conditions. Compare the low leakage specifications against circuit requirements to maintain signal integrity.

Single Zener Diodes Part Context

This part belongs to the 1N5239 series of low-power Zener diodes manufactured by Central Semiconductor. These components are widely used in legacy and modern electronics where reliable voltage stabilization is critical. The DO-35 form factor allows for easy integration into printed circuit boards utilizing standard through-hole assembly techniques.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering identical 9.1 V Zener diodes in DO-35 packages. Verify that substitute parts meet or exceed the original 500 mW power rating and operational temperature limits before implementation.
