1N4689-TP

Single Zener Diodes Overview

The MMSZ4689-TP is a silicon Zener diode manufactured by Micro Commercial Components (MCC). It provides a nominal Zener voltage of 5.1 V with a standard tolerance of ±5%. The device is rated for a maximum steady-state power dissipation of 500 mW at a lead temperature below 75°C and a junction temperature up to 200°C. It features a reverse leakage current of 10 µA measured at 3 V. The component utilizes a DO-35 axial through-hole package.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction with double slug type case
• Very sharp reverse characteristic for precise voltage regulation
• High reliability suitable for demanding environments

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Voltage reference applications
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as options include Tape & Reel, Ammo Packing, or Bulk quantities. Ensure compliance with RoHS3 standards and check for the Lead in Glass exemption status. Confirm authenticity by purchasing from authorized distributors to avoid counterfeit components.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V reference with ±5% tolerance is required in an axial package. Consider the 500 mW power rating and 200°C junction temperature limit for thermal management. Verify that the DO-35 form factor fits the board layout constraints compared to surface mount alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N4678 through 1N4717 series of 500 mW silicon Zener diodes produced by MCC. The series covers a wide voltage range from 1.8 V to 43 V. The -TP suffix indicates a specific packaging configuration available from the manufacturer.

Single Zener Diodes Replacement Considerations

Direct replacement options include parts from other manufacturers offering equivalent 5.1 V Zener characteristics in a DO-35 package. Verify pinout compatibility and ensure the substitute meets the same 500 mW power dissipation and hermetic sealing requirements.
