1N4099 TR TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4099 TR TIN/LEAD is a Zener diode with a nominal voltage of 6.8 V and a power dissipation rating of 250 mW. It features a 5% tolerance, a maximum reverse leakage current of 10 µA, and a Zener impedance of 200 ohms. The device operates within a temperature range of -65 °C to +200 °C and utilizes a DO-35-2 through-hole package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via internal metallurgical bonding for high reliability.
• Operates at elevated temperatures up to 200 °C junction temperature.
• Features low noise density characteristics suitable for precision applications.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Precision voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' against official datasheets to confirm reel packaging versus bulk availability. Confirm RoHS compliance status as tin/lead variants may differ from lead-free specifications. Ensure the manufacturer designation matches Central Semiconductor Corp rather than other entities using similar part numbers.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V Zener reference is required in a small axial glass package. Consider the 250 mW power limit and 200 °C thermal capability for harsh environments. Verify that the 200 ohm impedance meets circuit sensitivity requirements compared to lower impedance alternatives.

Single Zener Diodes Part Context

This component belongs to the JEDEC registered 1N4099 series of 500 mW metallurgically bonded glass Zener diodes. While standard versions often carry higher ratings, this specific variant is documented with 250 mW dissipation. The series includes MIL-qualified levels for high-reliability applications.

Single Zener Diodes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with 1N4099-1 or 1N4735A only if electrical parameters and package compatibility are verified against official manufacturer data.
