1N4681-TP

Overview

The 1N4681-TP is a 500mW silicon Zener diode manufactured by Micro Commercial Components. It features a nominal Zener voltage of 2.4V with a standard tolerance of ±5%. The device operates within a junction temperature range up to 200°C and a storage temperature range from -65°C to 200°C. It utilizes a DO-35 glass axial leaded package, which is hermetically sealed. Electrical characteristics include a maximum forward voltage of 1.5V at 100mA and a maximum reverse leakage current of 2.0µA.

Feature Summary

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

Applications

• Voltage regulation in electronic circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify the authenticity of the component through authorized distributors or direct manufacturer channels to avoid counterfeit parts. Confirm that the ordering suffix matches the required packaging format, such as tape and reel or bulk, as specifications may vary based on the specific procurement configuration.

Selection Notes

Select this component when a low nominal Zener voltage near 2.4V is required with a 500mW power dissipation rating. Ensure the application environment supports the specified thermal limits and that the DO-35 through-hole package fits the design constraints. Consider the sharp reverse characteristic for applications demanding tight voltage control.

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 range of Zener voltages from 1.8V to 43V, all sharing similar mechanical and electrical performance profiles within the DO-35 package form factor.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4681 equivalents in the DO-35 package. Verify that substitute parts meet the same 500mW power rating, 2.4V nominal voltage, and ±5% tolerance requirements.
