1N4626 BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4626 BK TIN/LEAD is a single axial-lead Zener diode housed in the DO-35 package. It features a nominal Zener voltage of 5.6 V with a tight tolerance of ±2%. The device supports a maximum power dissipation of 0.25 W and operates within an extended temperature range from -65 °C to +200 °C. Key electrical characteristics include a maximum dynamic impedance of 1400 Ω and a test current of 0.25 mA. The component utilizes tin/lead terminal plating for through-hole mounting applications.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a narrow ±2% tolerance on the 5.6 V reference point.
• Capable of sustained operation at elevated temperatures up to 200 °C.
• Utilizes a standard DO-35 axial leaded form factor for reliable through-hole integration.

Single Zener Diodes Applications

• Precision voltage reference circuits requiring low tolerance stability.
• Over-voltage protection stages in sensitive electronic systems.
• Clamping applications in analog signal processing paths.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm the tin/lead composition and packaging format. Ensure that the procurement specifications align with the required ±2% voltage tolerance and thermal ratings. Confirm RoHS compliance status if restricted substances are mandated by the end-use application standards.

Single Zener Diodes Selection Notes

Select this component when a stable 5.6 V reference is needed with tighter accuracy than standard 5% variants. The high maximum operating temperature of 200 °C makes it suitable for harsh environments where standard silicon limits would be exceeded. Verify that the 0.25 W power rating meets the thermal dissipation requirements of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N46xx series of small-signal Zener diodes manufactured by Central Semiconductor. These components are designed for general-purpose voltage regulation and clamping tasks. The specific model distinguishes itself through its tighter 2% voltage tolerance compared to standard industrial grades, offering enhanced precision for critical reference applications.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 5.6 V Zener voltage, 0.25 W power rating, and ±2% tolerance. Verify pinout compatibility with the DO-35 package. Check that replacement parts support the same maximum operating temperature of 200 °C and similar dynamic impedance characteristics to ensure circuit performance parity.
