1N4695

Overview

The onsemi 1N4695 is a single silicon Zener diode configured for voltage regulation. It features a nominal Zener voltage of 8.7V with a standard tolerance of 5%. The device is designed for surface mount applications in the DO-35 glass package, offering two pins. It supports a maximum power dissipation of 0.5W and operates within a temperature range from -55°C to 175°C.

Feature Summary

• Provides stable voltage regulation at a nominal 8.7V reference level
• Utilizes a hermetically sealed glass axial-leaded DO-35 package for environmental protection
• Supports high junction temperatures up to 175°C for robust thermal performance

Applications

• General-purpose voltage regulation circuits
• Reference voltage sources in electronic systems
• Overvoltage protection stages

Procurement Notes

Verify the specific manufacturer source when ordering, as the 1N4695 designation is utilized by multiple semiconductor vendors including onsemi, Central Semiconductor, and Microsemi. Confirm that the required package matches the DO-35 specification and ensure the voltage tolerance aligns with the 5% standard unless a tighter variant is explicitly specified in the design requirements.

Selection Notes

Select this component for low-power applications requiring a precise 8.7V reference point. The 0.5W power rating limits its use to moderate current scenarios. Ensure the circuit design accounts for the thermal characteristics of the glass DO-35 package and verify compatibility with the intended operating temperature range of -55°C to 175°C.

Part Context

This component belongs to the broader family of 500mW axial-leaded Zener diodes. It serves as a fundamental discrete semiconductor device for maintaining constant voltage levels across varying load conditions. The DO-35 package is a standard form factor widely recognized in through-hole and certain surface-mount assembly processes for reliable voltage clamping.

Replacement Considerations

Direct substitutes include parts from other manufacturers using the same JEDEC designation, such as Central Semiconductor's 1N4695TRLEADFREE or Microsemi's 1N4696-1E3 variants, provided they meet the identical 8.7V and 0.5W specifications.
