1N4106

Single Zener Diodes Overview

The Microchip Technology 1N4106 is a 500 mW Zener voltage regulator diode housed in an axial-lead glass DO-35 package. It provides a nominal Zener voltage of 12 V with a standard tolerance of ±5%. The device operates within a temperature range of -65 °C to +175 °C and features a maximum reverse leakage current of 9.2 µA at the specified voltage. Electrical characteristics include a test current of 250 µA, a dynamic impedance of 0.05 Ohms, and a positive temperature coefficient of +0.080 %/°C.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced reliability
• Hermetically sealed glass DO-35 package design
• Qualified per MIL-PRF-19500/435 for high-reliability applications

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (e.g., JAN, JANTX, JANTXV, or JANS) as these prefixes define the reliability standards. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from military qualifications. Ensure the package type aligns with the intended mounting method, as surface mount variants exist under different part numbers.

Single Zener Diodes Selection Notes

Select this component when a stable 12 V reference is required in harsh environments. The positive temperature coefficient indicates voltage increases with temperature. Verify that the power dissipation requirements are met by derating the 500 mW rating according to ambient temperature conditions. Consider the low dynamic impedance for applications requiring precise voltage stability under varying load currents.

Single Zener Diodes Part Context

This component belongs to the 1N4099-1 through 1N4135-1 series of 500 mW metallurgically bonded glass Zener diodes. The series offers voltages from 1.8 V to 100 V with various tolerance options. The 1N4106 specifically targets the 12 V segment of this lineup, providing a standardized solution for precision regulation tasks within the broader family of hermetically sealed axial-lead regulators.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' JEDEC registered 1N4106 parts. For military specifications, equivalent parts must meet MIL-PRF-19500/435 standards. Surface mount equivalents are available in the DO-213AA package format.
