1EZ100D10E3/TR12

Overview

The 1EZ100D10E3/TR12 is a silicon Zener diode manufactured by Microsemi Corporation. It provides voltage regulation with a nominal Zener voltage of 100 V and a tolerance of ±10%. The device has a maximum power dissipation rating of 1 W and operates within a temperature range of -65°C to 150°C. It features a forward voltage of 1.2 V at 200 mA. The component is housed in a DO-204AL (DO-41) axial plastic package and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation for circuit protection applications
• Utilizes a plastic encapsulated DO-204AL axial leaded package
• Operates reliably across an extended industrial temperature range

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify the specific suffix 'E3' indicates RoHS compliance status, as some Microsemi documentation lists this series as non-compliant. Confirm the 'TR12' designation corresponds to the correct tape and reel quantity. Check current availability status as the base part number may be subject to discontinuation notices.

Selection Notes

Select this component when a 100 V Zener voltage with 10% tolerance is required. Ensure the 1 W power rating suits the thermal environment. Verify that the axial DO-204AL package fits the board layout constraints compared to surface mount alternatives.

Part Context

This part belongs to the Microsemi 1EZ series of 1 Watt Zener Diodes. The series offers extensive voltage selections from 3.3 to 100 volts. Variants are available with different tolerances and screening levels, including military equivalents, to meet diverse application requirements.

Replacement Considerations

Equivalent parts include the 1N4754A series for standard tolerance or the 1EZ100D series for similar specifications. Verify pinout compatibility and thermal characteristics before substitution.
