1EZ100DE3/TR12

Overview

The Microsemi Corporation 1EZ100DE3/TR12 is a silicon Zener diode housed in the DO-41 axial plastic package. It provides a nominal Zener voltage of 100 V with a tolerance of ±20%. The device supports a maximum power dissipation of 1 W and operates within a junction temperature range of -65°C to +150°C. It features a matte tin (Sn) terminal finish, indicating RoHS compliance, and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Utilizes a plastic encapsulated DO-41 axial lead construction for flexible mounting
• Features moisture classification Level 1 requiring no dry pack storage

Applications

• General purpose voltage regulation circuits
• Power supply reference voltage generation
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix 'e3' confirms the matte tin terminal finish and RoHS compliance status required for your assembly process. Confirm that the 'TR12' designation matches the required tape and reel packaging format for automated insertion equipment. Ensure the component meets all environmental regulations applicable to your final product deployment region.

Selection Notes

Select this component when a 100 V regulation point is required in a standard axial package. The ±20% tolerance makes it suitable for applications where precise voltage accuracy is not critical. Consider the 1 W power rating and thermal management requirements for high-current operation scenarios.

Part Context

This part belongs to the Microsemi 1EZ series of 1-watt silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V in the DO-41 plastic package. Variations in the suffix indicate different voltage tolerances and terminal finishes, allowing designers to choose specific performance levels for their designs.

Replacement Considerations

Equivalent parts include the 1N4754A series for similar voltage regulation needs. Verify that any substitute maintains the DO-41 package dimensions and 1 W power dissipation rating to ensure mechanical and thermal compatibility.
