1N4694 TR PBFREE

Overview

The Central Semiconductor Corp 1N4694 TR PBFREE is a low-noise Zener diode designed for through-hole mounting in the DO-35 package. It features a nominal voltage of 8.2 V with a tolerance of ±5% and a power dissipation rating of 500 mW. The device operates within a reverse leakage current specification of 10 µA maximum. This component is manufactured using silicon technology and complies with RoHS standards, offering a reliable solution for voltage regulation applications requiring stable performance.

Feature Summary

• Low noise operation suitable for sensitive circuits
• Through-hole DO-35 axial leaded package
• Silicon planar construction

Applications

• Voltage reference circuits
• General purpose voltage regulation
• Protection against overvoltage transients

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the manufacturer is Central Semiconductor Corp to ensure authenticity. Check datasheets for exact electrical limits relevant to your thermal environment. Ensure compatibility with automated assembly processes if reel packaging is required for production lines.

Selection Notes

Select this component when a standard 8.2 V Zener voltage is required in a through-hole configuration. Consider the 500 mW power rating for thermal management in the design phase. Compare leakage current specifications against other series if ultra-low noise is critical. Verify that the DO-35 footprint matches the PCB layout constraints.

Part Context

This part belongs to the 1N4694 series of Zener diodes produced by Central Semiconductor. It is distinct from surface mount variants like CMHZ4694 or different manufacturers' equivalents such as Microchip's 1N4694UR-1. The series provides standardized voltage regulation capabilities for discrete electronic designs.

Replacement Considerations

Direct substitutes include other 1N4694 variants from different manufacturers, provided they meet the 8.2 V nominal voltage, 500 mW power dissipation, and DO-35 package requirements. Verify pinout and electrical tolerances match before substitution.
