1N4695

Overview

The Microchip Technology 1N4695 is a 0.5-watt axial-leaded Zener voltage regulator diode housed in a hermetically sealed glass DO-7 (DO-204AA) package. It provides an 8.7-volt nominal Zener voltage with a standard tolerance of plus or minus 5%. The device operates within a temperature range of -65°C to +175°C and features internally solder-bonded terminals for high reliability.

Feature Summary

• Hermetically sealed glass axial-lead construction
• Internally solder bonded for enhanced mechanical stability
• Inherently radiation hard design
• ESD nonsensitive per MIL-STD-750 Method 1020

Applications

• Voltage regulation over broad operating current ranges
• Temperature compensation circuits
• Reference voltage sources in harsh environments

Procurement Notes

Verify the specific manufacturer origin, as the 1N4695 designation is JEDEC registered and produced by multiple vendors including Microsemi and Microchip. Confirm that the component matches the required DO-7 package dimensions and lead plating specifications. Ensure the selected unit meets the necessary military screening prefixes if applicable.

Selection Notes

Select this component when a robust, low-power Zener diode is needed for through-hole mounting. Consider the tight reverse leakage characteristics at higher voltages. Evaluate thermal derating requirements based on the FR4 PCB copper pad configuration versus free-air conditions.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500 mW silicon Zener diodes. The series covers a voltage selection from 1.8 to 43 volts. These devices are designed for applications requiring high reliability and stable voltage regulation in demanding industrial and aerospace environments.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4695 variants meeting JEDEC standards. Surface mount equivalents are available in the DO-213AA outline under the 1N4695UR designation.
