1N4108/TR

Single Zener Diodes Overview

The Microchip Technology 1N4108/TR is a 500 mW Zener diode with a nominal voltage of 14 V and a standard tolerance of ±5%. It utilizes an internal metallurgical bond within a hermetically sealed axial-lead glass DO-35 (DO-204AH) package. The device operates across a temperature range of -65°C to +175°C, featuring a maximum reverse leakage current of 50 nA at 10.7 V and a dynamic impedance of 200 Ohms. The 'TR' suffix indicates tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Hermetically sealed construction using an internal metallurgical bond for high reliability.
• Flexible axial-lead mounting terminals suitable for through-hole applications.
• Capable of regulating voltage over broad ranges of current and temperature.

Single Zener Diodes Applications

• Voltage regulation in circuits requiring stable reference voltages.
• High-reliability electronic systems utilizing MIL-PRF-19500/435 qualified components.
• Temperature-compensated circuit designs.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm the presence of the tape and reel packaging configuration. Ensure that the required reliability level matches the commercial grade specifications associated with this part number variant. Confirm compliance requirements against project standards prior to procurement.

Single Zener Diodes Selection Notes

Select this component when a 14 V Zener reference is required in an axial-lead form factor. The metallurgical bond provides robustness for demanding environments. Verify that the 500 mW power dissipation rating aligns with the thermal design constraints of the target application board.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes manufactured by Microchip Technology. These components are JEDEC registered and offer extensive voltage selection from 1.8 to 100 volts. The series supports various tolerance levels and packaging options including surface mount variants.

Single Zener Diodes Replacement Considerations

The 1N4108/TR serves as a parameter-equivalent replacement for the standard 1N4108 diode. Both share identical electrical characteristics and package dimensions, differing primarily in the bulk versus tape-and-reel packaging format.
