1N4680 BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4680 BK TIN/LEAD is a silicon planar Zener diode designed for through-hole mounting in DO-35-2 axial leaded packages. It provides a nominal Zener voltage of 10 V with a 5% tolerance and operates at a test current of 25 mA. The device dissipates up to 500 mW of power, maintains a maximum reverse leakage current of 5 µA, and exhibits a Zener impedance of 70 Ω. It supports continuous collector currents up to 430 mA and functions reliably within an extended temperature range from -65 °C to +200 °C junction temperature.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Features low reverse leakage current for high efficiency
• Supports high operating temperatures up to 200 °C

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify the specific suffix BK TIN/LEAD against official datasheets to confirm lead composition and package dimensions. Ensure compatibility with existing PCB footprints before procurement. Confirm RoHS compliance status if required by project specifications. Validate thermal management requirements for the 500 mW dissipation rating during operation.

Selection Notes

Select this component when a precise 10 V reference is needed in a standard axial package. Consider the 70 Ω impedance for dynamic load variations. Evaluate the 500 mW power rating against expected thermal conditions. Compare leakage characteristics with alternative series if ultra-low current drain is critical for the application design.

Part Context

This part belongs to the 1N46xx series of Zener diodes manufactured by Central Semiconductor Corp. These components are widely used in general-purpose electronic circuits requiring reliable voltage stabilization. The DO-35 package offers robust mechanical stability for through-hole assembly processes commonly found in industrial and consumer electronics manufacturing.

Replacement Considerations

Check for direct equivalents such as 1N4680B or generic 1N4680 variants. Verify that substitute parts match the 10 V Zener voltage, 500 mW power rating, and DO-35 package outline. Ensure electrical parameters like impedance and leakage current remain within acceptable tolerances for the specific circuit requirements.
