1EZ100D5/TR8

Overview

The Microsemi Corporation 1EZ100D5/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tolerance of ±5% and a maximum power dissipation rating of 1 W. The component utilizes a DO-204AL (DO-41) axial through-hole package, providing two terminals for circuit integration. It operates within a temperature range of -65°C to 150°C and exhibits a forward voltage of 1.2 V at 200 mA.

Feature Summary

• Provides stable voltage regulation with a 100 V nominal breakdown voltage
• Engineered for high-power operation up to 1 W with adequate heat sinking
• Features a robust plastic encapsulated DO-41 axial leaded construction

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Procurement Notes

Verify the specific suffix TR8 to confirm tape-and-reel packaging configuration prior to procurement. Confirm compliance requirements as the component is identified as non-RoHS compliant. Ensure the selected variant matches the required 100 V specification and 1 W power rating for the intended application design.

Selection Notes

Select this component when a 100 V Zener voltage with 5% tolerance is required in an axial package. Consider the 1 W power dissipation capability and the specified operating temperature range of -65°C to 150°C. Verify that the DO-204AL form factor fits the board layout constraints.
