1N4099 TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4099 TR PBFREE is a silicon Zener diode from the 1N4099 series, designed for low leakage, low current, and low noise applications. It features a nominal Zener voltage of 6.8 V with a 5% tolerance range (6.460 V to 7.140 V). The device operates in a DO-35 axial package with a maximum power dissipation of 250 mW at 25°C ambient temperature. Key electrical parameters include a test current of 250 μA, a maximum Zener impedance of 200 Ω, and a maximum reverse current of 10 μA at 5.2 V. It supports an operating junction temperature range of -65°C to +200°C.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm that the 'PBFREE' designation aligns with environmental compliance standards mandated by the end application. Ensure the component matches the exact 6.8 V specification and DO-35 package dimensions required by the design schematic.

Single Zener Diodes Selection Notes

Select this component when a precise 6.8 V reference is needed with minimal noise interference. The 250 mW power rating limits suitability to low-current applications only. Verify that the 200 Ω maximum impedance meets the dynamic stability requirements of the target circuit. Consider the DO-35 package constraints for PCB layout and thermal management during the selection phase.

Single Zener Diodes Part Context

This part belongs to the Central Semiconductor 1N4099 through 1N4135 series of silicon Zener diodes. The series covers a voltage range from 6.8 V to 100 V, all sharing similar low-noise characteristics and 5% tolerance specifications. The 1N4099 represents the lowest voltage option in this specific product line, utilizing the standard DO-35 axial leaded package format.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4099 equivalents in the DO-35 package. Ensure replacement parts maintain the 6.8 V nominal voltage, 5% tolerance, and comparable noise density specifications to preserve circuit performance.
