1N5234C

Single Zener Diodes Overview

The Fairchild Semiconductor 1N5234C is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a tolerance of ±2%. The device operates in an axial DO-35 package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum dynamic impedance of 7 Ω, a reverse leakage current of 5 µA at 3.5 V, and a forward voltage drop of 1.1 V at 200 mA. It supports a wide operating temperature range from -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with tight ±2% tolerance
• Capable of handling high thermal loads up to 200 °C
• Utilizes robust glass-passivated silicon construction

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Clamping and switching applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' to confirm the ±2% tolerance variant, as other suffixes like 'B' indicate different tolerances. Ensure the procurement documentation explicitly lists the DO-35 axial package and 500 mW power rating. Cross-reference the manufacturer part number against official datasheets to validate the 6.8 V nominal voltage and 7 Ω dynamic impedance specifications before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a stable 6.8 V reference is required with strict tolerance limits. The high maximum operating temperature makes it suitable for demanding environments where standard components may fail. Consider the low dynamic impedance for applications requiring minimal voltage variation under changing load conditions.

Single Zener Diodes Part Context

This component belongs to the 1N523x series of small-signal Zener diodes manufactured by Fairchild Semiconductor. These devices are widely used in general-purpose electronics for their reliability and consistent performance. The 1N5234C specifically targets applications needing tighter voltage accuracy compared to standard tolerance variants within the same family.

Single Zener Diodes Replacement Considerations

Equivalent parts must match the 6.8 V Zener voltage, 500 mW power dissipation, and ±2% tolerance. Verify that substitute components utilize the DO-35 axial package and support the same temperature range. Check dynamic impedance and leakage current specifications to ensure circuit compatibility.
