1N4703 BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4703 BK TIN/LEAD is a silicon unidirectional Zener diode designed for through-hole mounting in the DO-35 axial leaded package. It provides a nominal Zener voltage of 16 V with a tight tolerance of 2%. The component is rated for a maximum power dissipation of 0.5 W and operates within an extended temperature range from -65 °C to +200 °C junction temperature. It features a single configuration with two terminals, utilizing tin/lead plating for reliable soldering connections.

Single Zener Diodes Feature Summary

• High thermal stability supporting operation up to 200 °C junction temperature
• Precision voltage regulation with 2% tolerance for critical reference applications
• Robust construction in standard DO-35 axial package for easy circuit integration

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required lead finish and tolerance. Confirm that the 2% tolerance variant is explicitly requested, as standard versions may differ. Ensure the DO-35 package dimensions align with the target PCB footprint. Check RoHS compliance status if lead-free requirements are mandatory for the assembly process.

Single Zener Diodes Selection Notes

Select this component when a precise 16 V reference is needed with tighter than standard 5% tolerances. The high maximum operating temperature makes it suitable for harsh environments where standard diodes might fail. Ensure the 0.5 W power rating accommodates the expected dissipation in the specific circuit design without exceeding thermal limits.

Single Zener Diodes Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Central Semiconductor. These components are widely used in general-purpose electronics for voltage regulation and protection. The 1N4703 specifically targets applications requiring higher precision than the common 5% tolerance variants offer.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 16 V Zener voltage, 0.5 W power rating, and DO-35 package. Verify that substitute parts also offer 2% tolerance if precision is critical. Ensure the replacement supports the same -65 °C to +200 °C operating temperature range.
