1N4110UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4110UR-1/TR is a surface mount Zener diode in the DO-213AA package. It provides an 8.2V nominal voltage with 5% tolerance and 200 Ohms impedance at a 250 µA test current. The device dissipates 500 mW, operates from -65°C to +175°C, and features low noise density of 40 µV/√Hz.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF package with internal metallurgical bond
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels
• Inherently radiation hard and non-sensitive to ESD per MIL-STD-750 method 1020

Single Zener Diodes Applications

• High reliability voltage regulation
• Radiation-hardened electronic circuits
• Temperature-compensated reference applications

Single Zener Diodes Procurement Notes

Verify the specific military qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple screening grades. Confirm RoHS compliance status, noting that commercial versions may differ from qualified military units. Ensure the TR suffix matches the required tape and reel packaging specifications.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability environments. The 1N4110 variant offers an 8.2V breakdown suitable for mid-range regulation needs. Consider the 500 mW power dissipation and wide temperature range for thermal management planning.

Single Zener Diodes Part Context

This device belongs to the 1N4099 through 1N4135 series of 500 mW metallurgically bonded glass surface mount Zener diodes. These components serve as surface mount equivalents to traditional axial-leaded JEDEC registered parts, providing a compact solution for space-constrained designs requiring robust performance.

Single Zener Diodes Replacement Considerations

Commercial equivalents are available under the CDLL prefix, such as CDLL4110-1. For direct replacements within the same family, verify the specific tolerance and impedance requirements match the original design constraints.
