1N4694-TP

Overview

The MCC 1N4694-TP is a silicon Zener diode with a nominal voltage of 8.2 V and a standard tolerance of ±5%. It operates in the DO-35 axial through-hole package, featuring hermetically sealed glass construction. The device supports a maximum steady-state power dissipation of 500 mW at temperatures below 75°C. Electrical characteristics include a maximum forward voltage of 1.5 V at 100 mA and a reverse leakage current of 1.0 µA measured at 7.5 V.

Feature Summary

• Hermetically sealed double slug type glass construction for high reliability
• Sharp reverse characteristic curve for precise voltage regulation
• Standard ±5% tolerance on nominal Zener voltage

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm compliance with RoHS directives and check for specific suffixes indicating tape and reel or bulk packaging options before ordering.

Selection Notes

Select this component for general-purpose voltage regulation requiring a stable 8.2 V reference. Ensure the circuit design accommodates the 500 mW power dissipation limit and verify that the DO-35 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500 mW silicon Zener diodes manufactured by Micro Commercial Components. The series covers a wide range of voltages from 1.8 V to 43 V, utilizing consistent mechanical data and electrical testing standards across all variants.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4694 equivalents meeting identical 8.2 V, 500 mW, and DO-35 specifications. Verify pinout compatibility and thermal resistance values when cross-referencing datasheets.
