1N4110DUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4110DUR-1/TR is a surface mount Zener diode in the DO-213AA package. It features a nominal voltage of 16V with a 1% tolerance and a maximum impedance of 100 Ohms. The device operates at a test current of 250 µA, has a maximum reverse leakage of 50 nA at 12.2V, and dissipates up to 500 mW. It supports temperatures from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA package with internal metallurgical bond
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels
• Inherently radiation hard design suitable for high reliability applications

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability aerospace and defense circuits
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify that the TR suffix indicates tape and reel packaging per EIA-481-1-A standards. Confirm the specific military qualification level (JAN, JANTX, JANTXV, or JANS) required for the application. Ensure compatibility with the hermetically sealed glass construction and tin-lead plating specifications.

Single Zener Diodes Selection Notes

Select this component when a 16V Zener reference with tight 1% tolerance is needed in a surface mount form factor. The DO-213AA package provides a direct equivalent to the axial 1N4110 series while offering hermetic sealing. Consider the radiation hardness and wide operating temperature range for demanding environments.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR-1 through 1N4135UR-1 series of 500 mW metallurgically bonded glass surface mount Zener diodes. These devices are designed as surface mount equivalents to standard JEDEC registered axial leaded Zener diodes, providing hermetic sealing and high reliability for specialized industrial and military use cases.

Single Zener Diodes FAQ

What does the 'TR' suffix indicate for this part number?

The 'TR' suffix indicates that the device is supplied in tape and reel packaging according to EIA-481-1-A standards.

How is the polarity identified on the DO-213AA package?

Polarity is indicated by a cathode band on one end of the glass package; the banded end must be positive with respect to the opposite end for Zener regulation.
