1N4109-TP

Single Zener Diodes Overview

The 1N4109-TP is a silicon unidirectional Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 15V with a standard tolerance of ±5%. The device is housed in a hermetically sealed glass DO-35 package and supports a maximum steady-state power dissipation of 500 mW at a lead temperature below 75°C. It operates within a junction temperature range up to 175°C and includes a metallurgical bonded construction.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection
• Metallurgically bonded internal structure
• Standard 5% voltage tolerance for reliable regulation

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the authenticity of the component through authorized MCC distributors or direct procurement channels. Ensure the ordering suffix matches the required packaging format, such as tape and reel or bulk, as specified in the manufacturer's documentation. Confirm compliance with RoHS standards and check for any specific handling requirements related to the hermetic glass package.

Single Zener Diodes Selection Notes

Select this component when a 15V regulation point is required in a through-hole axial configuration. Consider the 500mW power rating and the thermal resistance characteristics for heat management. Verify that the operating environment does not exceed the specified maximum junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4125 series of 500mW silicon Zener diodes produced by Micro Commercial Components. The series offers a wide range of nominal voltages from 1.8V to 47V, all sharing the same DO-35 glass package and general electrical characteristics defined in the common datasheet.

Single Zener Diodes Replacement Considerations

Compatible replacements include other manufacturers' equivalents designated as 1N4109 or 1N4109E3. Verify that substitute parts meet the identical 15V nominal voltage, 500mW power dissipation, and DO-35 package dimensions.
