1EZ100D/TR12

Overview

The 1EZ100D/TR12 is a silicon Zener diode manufactured by Microsemi Corporation, designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tolerance of ±20% and a maximum power dissipation of 1 W. The device utilizes a DO-204AL (DO-41) axial-leaded plastic package suitable for through-hole mounting. It operates within a temperature range of -65°C to 150°C and exhibits a forward voltage of 1.2 V at 200 mA. The component is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation with a nominal breakdown voltage of 100 V
• Capable of handling up to 1 W of power dissipation under adequate heat sinking conditions
• Constructed with a plastic encapsulated DO-41 axial leaded body for robust mechanical support

Applications

• General purpose voltage regulation circuits
• Overvoltage protection stages
• Reference voltage generation in electronic systems

Procurement Notes

Verify the specific suffix TR12 against official Microsemi documentation to confirm the tape and reel packaging configuration. Confirm RoHS compliance status as sources indicate non-compliance. Check current product lifecycle status as this item may be discontinued or subject to change without notice.

Selection Notes

Select this component when a 100 V Zener reference with 1 W power rating is required in an axial package. Ensure the circuit design accommodates the ±20% voltage tolerance. Verify thermal management requirements for continuous operation at full power dissipation within the specified temperature range.

Part Context

This part belongs to the 1EZ series of silicon Zener diodes from Microsemi. The series offers various voltage options ranging from 3.3 V to 200 V in both glass and plastic packages. The 1EZ variant specifically denotes the plastic encapsulated DO-41 construction, distinguishing it from hermetic glass versions like the 1N59xxBG series.
