1N4686-TP

Single Zener Diodes Overview

The MCC 1N4686-TP is a silicon Zener diode with a nominal voltage of 3.9V and a tolerance of ±5%. It operates in the DO-35 axial leaded package, providing a maximum steady-state power dissipation of 500 mW at a lead temperature below 75°C. The device features a hermetically sealed double-slug glass construction and supports a junction temperature up to 200°C.

Single Zener Diodes Feature Summary

• Hermetically sealed double-slug type glass construction
• Very sharp reverse characteristic for precise regulation
• Standard ±5% tolerance on nominal Zener voltage

Single Zener Diodes Applications

• Voltage regulation over broad operating current ranges
• Reference voltage generation in electronic circuits
• Overvoltage protection applications

Single Zener Diodes Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm compliance with RoHS standards and check for specific suffix designations that may indicate alternative packaging formats such as tape and reel or bulk options.

Single Zener Diodes Selection Notes

Select this component when a standard 3.9V reference is required in an axial leaded form factor. Ensure the circuit design accommodates the 500mW power rating and verify that the operating temperature range aligns with the specified -65°C to 200°C limits.

Single Zener Diodes Part Context

This part belongs to the 1N4678 through 1N4717 series of 500mW Silicon Zener Diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 1.8V to 43V, utilizing the standard DO-35 package for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same manufacturer family include variants sharing the 1N4686 designation. Cross-manufacturer replacements must match the 3.9V nominal voltage, 500mW power rating, and DO-35 package outline.
