1N4684-TP

Overview

The 1N4684-TP is a 500mW silicon Zener diode manufactured by Micro Commercial Components. It features a nominal Zener voltage of 3.3V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65°C to +200°C and utilizes a DO-35 axial through-hole package. Key electrical characteristics include a maximum forward voltage of 1.5V at 100mA, a maximum reverse leakage current of 7.5µA, and a maximum Zener current rating of 80mA.

Feature Summary

• Hermetically sealed glass construction for high reliability
• Very sharp reverse characteristic for precise regulation
• Lead-free finish compliant with RoHS directives

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify the authenticity of the component by checking for official MCC markings and purchasing from authorized distributors. Confirm that the specific suffix matches the required packaging format, such as tape and reel or bulk, as these affect handling procedures. Ensure compliance with environmental regulations relevant to your region before finalizing procurement.

Selection Notes

Select this component when a stable 3.3V reference is required in low-power applications. Consider the ±5% tolerance and thermal resistance specifications during circuit design. Evaluate the maximum surge power capabilities if transient protection is needed. Ensure the operating environment stays within the specified temperature limits to maintain performance.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500mW silicon Zener diodes produced by Micro Commercial Components. The series covers a wide voltage range from 1.8V to 43V, sharing common mechanical and thermal characteristics. These components are designed for general-purpose voltage regulation and protection tasks in electronic circuits.

Replacement Considerations

Compatible replacements include other manufacturers' 1N4684 variants that meet the same 3.3V nominal voltage, 500mW power dissipation, and DO-35 package requirements. Verify that substitute parts offer equivalent reverse leakage current and Zener impedance specifications to ensure circuit compatibility.
