1N4110-1

Single Zener Diodes Overview

The Microchip Technology 1N4110-1 is a 500 mW metallurgically bonded glass Zener diode in the axial-leaded DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 16 V with a standard tolerance of ±5%. The device operates within a junction and storage temperature range of -65°C to +175°C. Key electrical characteristics include a maximum dynamic impedance of 0.05 Ohms, a reverse leakage current of 12.2 µA at 12.2 V, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

Single Zener Diodes Applications

• High-reliability voltage regulation circuits
• Military and aerospace electronic systems
• Precision reference voltage sources

Single Zener Diodes Procurement Notes

Verify that the specific order matches the required military qualification level (JAN, JANTX, JANTXV, or JANS), as these designations indicate distinct reliability standards rather than functional differences. Confirm compliance requirements, noting that RoHS compliant versions are available only on commercial grade parts. Ensure the procurement documentation aligns with the specified JEDEC registered part number and package style.

Single Zener Diodes Selection Notes

Select this component when a 16 V Zener reference is needed in a through-hole axial package. The 1N4110-1 offers low dynamic impedance suitable for precision applications. Consider alternative series members if different voltage ratings are required. Verify thermal derating requirements against the application's ambient temperature conditions to ensure the 500 mW power rating remains sufficient.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener diodes. These components share common construction features, including the DO-35 glass package and metallurgical bonding technology. The series covers a wide voltage range from 1.8 V to 100 V, allowing designers to select appropriate breakdown voltages while maintaining consistent package and reliability characteristics.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4110 equivalents meeting the same electrical specifications. For military-grade requirements, verify that any replacement meets the specific MIL-PRF-19500/435 qualification level intended for the original design.
