1N4683 BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4683 BK TIN/LEAD is a single Zener diode housed in a DO-35-2 through-hole package. It features a nominal Zener voltage of 3V with a 5% tolerance and a maximum reverse leakage current of 0.8 µA. The device has a reverse voltage of 1V, a forward current rating of 85 mA, and a power dissipation capacity of 500 mW.

Feature Summary

• Provides stable voltage regulation at a 3V nominal level
• Constructed with tin-lead terminated leads for reliable soldering
• Designed for through-hole mounting in standard DO-35 packages

Applications

• Voltage reference circuits requiring 3V stability
• Overvoltage protection for low-voltage signal lines
• Clamping applications in analog signal processing

Procurement Notes

Verify the specific ordering suffix to confirm lead-free or tin-lead composition, as variations exist within the product line. Ensure the DO-35 package style matches your PCB footprint requirements. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and exact electrical tolerances before finalizing procurement plans.

Selection Notes

Select this component when a precise 3V Zener reference is needed in a through-hole assembly. The 500mW power rating supports moderate current handling compared to lower-power variants. Verify that the 0.8 µA leakage current meets the sensitivity requirements of your specific circuit design.

Part Context

This component belongs to the 1N468x series of axial-lead Zener diodes manufactured by Central Semiconductor. These devices are commonly used in general-purpose electronics where reliable voltage regulation is required. The series offers various voltage options within the same physical package form factor.

Replacement Considerations

Equivalent parts include other 3V Zener diodes in the DO-35 package with similar 500mW ratings. Verify pinout compatibility and thermal characteristics when substituting.
