1N4110/TR

Single Zener Diodes Overview

The Microchip Technology 1N4110/TR is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 16 V at a test current of 250 µA, with a maximum dynamic impedance of 0.05 Ohms and a maximum reverse leakage current of 12.2 µA. The device operates within a junction temperature range of -65 °C to +175 °C and features a positive temperature coefficient of +0.085 %/°C.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for high reliability
• Hermetically sealed glass DO-35 axial-lead package
• Low noise density characteristics suitable for precision regulation

Single Zener Diodes Applications

• High reliability applications requiring MIL-PRF-19500/435 qualification levels
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required tolerance level, as standard JEDEC versions typically carry a 5% voltage tolerance. Confirm RoHS compliance status if applicable, noting that certain finishes or compliance markings may vary by manufacturing lot. Ensure the ordering suffix correctly identifies the tape and reel packaging configuration.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed axial-lead Zener diode with a 500 mW power rating is required. Consider the positive temperature coefficient for circuits operating above 6.8 V. Verify that the lead length and package dimensions fit the target PCB layout constraints for the DO-35 style housing.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener regulators manufactured by Microchip Technology. These components are designed for robust performance in demanding environments, offering extensive voltage selection from 1.8 to 100 volts with various tolerance options available across the product family.

Single Zener Diodes Replacement Considerations

Consult official documentation for parameter-equivalent substitutes such as the 1N4110DUR-1/TR variant, which offers surface mount compatibility while maintaining similar electrical specifications.
