1N4106 (DO35)

Single Zener Diodes Overview

The Microsemi Corporation 1N4106 is a silicon Zener diode with a nominal voltage of 12V and a maximum power dissipation of 0.5W. It utilizes an internal metallurgical bond within a hermetically sealed glass DO-35 (DO-204AH) axial-lead package. The device operates across a junction temperature range of -65°C to +175°C, features a maximum dynamic impedance of 200 Ω at a test current of 250 µA, and maintains a noise density of 40 µV/√Hz.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced structural integrity
• Hermetically sealed glass DO-35 axial-lead package
• Qualified per MIL-PRF-19500/435 for high reliability applications
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation in military-grade electronic systems
• High-reliability aerospace circuitry
• Low-noise reference voltage generation
• Radiation-hardened protection circuits

Single Zener Diodes Procurement Notes

Verify the specific qualification level required, as the 1N4106 series is available in JAN, JANTX, JANTXV, and JANS variants. Confirm whether RoHS compliance is necessary, noting that commercial versions may differ from military-qualified parts. Ensure the ordering suffix matches the desired tolerance and packaging configuration before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 12V reference is needed in harsh environments requiring radiation hardness. The DO-35 package supports flexible axial-lead mounting. Consider tighter tolerance suffixes if standard 5% accuracy is insufficient. Verify thermal derating requirements against the application's ambient temperature conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4099 through 1N4135 series of 500 mW Zener voltage regulators manufactured by Microsemi. These devices are designed for broad voltage selection ranging from 1.8 to 100 volts. The series is widely used in applications demanding high reliability and low noise performance.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' 1N4106 equivalents meeting DO-35 specifications. For military applications, verify compatibility with MIL-PRF-19500/435 standards. Surface mount alternatives like the 1N4106DUR are available in the DO-213AA package.
