1N4106/TR

Single Zener Diodes Overview

The Microchip Technology 1N4106/TR 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 features a maximum dynamic impedance of 0.05 Ohms and a maximum reverse leakage current of 9.2 µA at the specified test voltage. Operating within a temperature range of -65 °C to +175 °C, it utilizes a metallurgically bonded construction for high reliability. The '/TR' suffix indicates tape and reel packaging.

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

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High-reliability military and aerospace circuits
• Low-noise reference applications

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (JAN, JANTX, JANTXV, or JANS) as commercial versions differ from mil-qualified parts. Confirm the presence of the '/TR' suffix ensures tape and reel packaging rather than bulk. Ensure compliance requirements align with the manufacturer's documentation for the specific revision.

Single Zener Diodes Selection Notes

Select this component when a 12 V Zener reference with low dynamic impedance is required in an axial-lead form factor. The metallurgically bonded design supports operation in harsh environments up to 175 °C. Consider the noise density specifications if used in sensitive analog signal paths requiring stable voltage references.

Single Zener Diodes Part Context

This part belongs to the 1N4099 through 1N4135 series of 500 mW Zener diodes manufactured by Microchip Technology. These devices are JEDEC registered and offer voltages ranging from 1.8 V to 100 V. The series is characterized by its internal metallurgical bonding and availability in various military reliability levels.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4106 variants such as JAN1N4106, JANTX1N4106, or JANS1N4106 depending on the required qualification level. Surface mount equivalents like the 1N4106UR-1 in DO-213AA packages may be considered if footprint changes are permissible.
