1N4695 TR PBFREE

Overview

The Central Semiconductor Corp 1N4695 TR PBFREE is a silicon Zener diode housed in the DO-35 axial glass package. It provides a nominal Zener voltage of 8.7 V with a maximum power dissipation of 0.25 W. The device maintains a tight tolerance of ±5% and operates within a temperature range of -55 °C to 175 °C. Designed for low-level regulation, it features a maximum reverse leakage current of 1 µA at 6.6 V. The component is supplied in tape and reel packaging for automated surface mount or through-hole assembly processes.

Feature Summary

• Utilizes a glass-passivated silicon junction for stable voltage regulation
• Provides precise voltage control with a narrow ±5% tolerance band
• Engineered for low-noise performance in sensitive signal paths
• Features an isolated case connection for safe circuit grounding

Applications

• Low-voltage reference circuits requiring stable DC levels
• Overvoltage protection stages for sensitive semiconductor inputs
• Clamping applications in analog signal conditioning networks
• Biasing elements in transistor amplifier configurations

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm the exact power rating and tolerance class. Ensure the procurement specification matches the required operating temperature range and package style. Confirm RoHS compliance status directly from the latest datasheet revision before finalizing orders.

Selection Notes

Select this component when a compact axial package is required for low-power voltage regulation tasks. Consider the 0.25 W power limit for thermal management in enclosed environments. Evaluate the reverse leakage characteristics against the noise requirements of the target application circuit to ensure signal integrity is maintained.

Part Context

This part belongs to the standard 1N4695 series of Zener diodes manufactured by Central Semiconductor Corp. It serves as a lead-free compliant alternative to older versions, adhering to modern environmental standards while maintaining traditional electrical specifications. The component is widely used in general-purpose electronics where reliable voltage clamping is necessary.

Replacement Considerations

Direct replacements include parts from other manufacturers sharing the 1N4695 designation, such as those from Micro Commercial Components or Panjit, provided they match the 8.7 V nominal voltage, 0.25 W power rating, and DO-35 package dimensions.
