1N4692 (DO35)

Single Zener Diodes Overview

The Microsemi Corporation 1N4692 is a silicon Zener diode housed in a hermetically sealed glass DO-35 axial leaded package. It provides a nominal Zener voltage of 6.8V with a standard tolerance of 5%. The device is rated for a maximum power dissipation of 0.5W and operates within a temperature range extending up to 175°C. Designed as a unidirectional voltage regulator, it utilizes an isolated case connection and metallurgical bonding to ensure reliability in demanding environments.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection
• Internal metallurgical bond for enhanced structural integrity
• Capable of regulating voltage across a broad operating current range

Single Zener Diodes Applications

• Voltage regulation in precision electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., -1, E3) to confirm metallurgical bonding status and RoHS compliance. Confirm that the DO-35 package matches the required footprint. Ensure the 6.8V rating aligns with circuit requirements. Check for military qualification levels if high reliability is necessary. Validate datasheet revisions for updated thermal characteristics.

Single Zener Diodes Selection Notes

Select this component when a low-power, hermetically sealed Zener diode is required. The DO-35 package suits through-hole mounting applications. Consider tighter tolerance variants if voltage accuracy is critical. Evaluate thermal derating curves for high-temperature operation. Compare against surface mount alternatives if space constraints exist.

Single Zener Diodes Part Context

This part belongs to the Microsemi 1N46xx series of 0.5W Zener diodes. These devices are widely used in commercial and industrial electronics. The series offers various voltage options from 1.8V to 100V. The DO-35 package is a standard industry form factor. Microsemi provides both commercial and qualified versions of these regulators.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N4692 diodes in DO-35 packages. Verify voltage tolerance and power rating compatibility. Ensure hermetic sealing requirements are met by the substitute. Check pinout and package dimensions for mechanical fit.
