1N4684 BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4684 BK TIN/LEAD is a through-hole Zener diode housed in a DO-35-2 package. It features a nominal Zener voltage of 3.3 V with a 5% tolerance and a power dissipation rating of 500 mW. The device operates within a temperature range of -65 °C to +200 °C, has a maximum reverse leakage current of 7.5 µA, and supports a forward current of 80 mA.

Feature Summary

• Provides stable voltage regulation at 3.3 V for circuit protection applications
• Capable of operating at elevated temperatures up to 200 °C
• Utilizes a glass-passivated junction for reliability

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm lead finish and packaging format. Ensure the component meets RoHS requirements if applicable to your assembly process. Cross-reference the Mouser number 610-1N4684BK-TL for accurate identification during sourcing.

Selection Notes

Select this component when a 3.3 V Zener voltage is required in a standard axial leaded package. Consider the 500 mW power rating and high maximum operating temperature of 200 °C for thermal management. Verify that the 7.5 µA leakage current specification aligns with the sensitivity requirements of the target application.

Part Context

This part belongs to the 1N4684 series of Zener diodes manufactured by Central Semiconductor. It is commonly available in bulk packaging and is designed for general-purpose voltage regulation tasks. The tin/lead finish indicates a specific terminal plating option distinct from lead-free variants.

Replacement Considerations

Equivalent parts include the 1N4684UR from Microsemi or Digitron, which share similar electrical characteristics but may differ in package style such as MELF or hermetic sealing.
