1N4110DUR-1

Single Zener Diodes Overview

The Microchip Technology 1N4110DUR-1 is a 500 mW metallurgically bonded glass surface mount Zener diode in the DO-213AA package. It provides a nominal Zener voltage of 16 V with a ±1% tolerance at a test current of 250 µA. The device features a maximum dynamic impedance of 100 Ohms and a reverse leakage current of 50 nA at 12.2 V. It operates within a junction temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF style package with internal metallurgical bond
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS reliability 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 requiring JANS qualification
• Reference voltage sources in radiation-hardened environments

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required military qualification level (JAN, JANTX, JANTXV, or JANS) as defined by the manufacturer's part nomenclature. Confirm RoHS compliance status if applicable, noting that certain environmental compliances may be restricted to commercial grades. Ensure the component meets the specific screening requirements mandated by the application environment before procurement.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode with precise voltage tolerance is required. The 16 V rating and 1% tolerance make it suitable for stable reference applications. Consider the DO-213AA package dimensions and the need for MIL-qualified reliability when evaluating alternatives. Verify thermal derating requirements against the operating ambient temperature conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR-1 through 1N4135UR-1 series of 500 mW Zener regulators. These components serve as surface mount equivalents to traditional axial-leaded JEDEC registered diodes. The series offers voltages from 1.8 to 100 V with various tolerance options, providing a standardized solution for replacing through-hole designs in compact surface mount layouts.
