1EZ100DE3/TR8

Overview

The 1EZ100DE3/TR8 is a single Zener diode manufactured by Microsemi Corporation, 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 device utilizes silicon as the semiconductor material and is housed in an axial-lead DO-204AL (DO-41) plastic package suitable for through-hole mounting. It operates within a temperature range of -65°C to 150°C and has a forward voltage of 1.2 V at 200 mA. This component is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Provides stable voltage regulation with a nominal breakdown voltage of 100 V and tight ±5% tolerance.
• Capable of handling a maximum power dissipation of 1 W for reliable operation in high-current scenarios.
• Constructed with silicon technology and encapsulated in a durable DO-204AL plastic housing.
• Supports extended operational environments with a wide junction temperature range from -65°C to 150°C.

Applications

• Voltage reference circuits requiring precise 100 V stabilization.
• Overvoltage protection stages in industrial electronic systems.
• Clamping applications in power supply output lines.

Procurement Notes

Verify compliance with current environmental directives, specifically RoHS status, as manufacturing standards may evolve. Confirm the specific suffix 'E3' indicates lead-free composition if required by assembly specifications. Check for end-of-life notices or obsolescence alerts directly from Microsemi before finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when a robust 100 V regulation point is needed in a standard axial package. Ensure the circuit design accommodates the 1 W power rating and that the operating temperature remains within the specified -65°C to 150°C range. Verify that the ±5% tolerance aligns with the system's voltage accuracy requirements.

Part Context

This part belongs to the Microsemi 1EZ series of single Zener diodes, which are engineered for general-purpose voltage regulation. The series offers various voltage options within the DO-204AL package, providing designers with standardized components for diverse voltage levels. The 'E3' suffix typically denotes a lead-free and RoHS-compliant variant within the product line.

Replacement Considerations

Direct substitutes include other 100 V, 1 W Zener diodes in the DO-41 package with comparable tolerance. Cross-reference with Microsemi's updated product portfolio for any newer equivalents. Ensure any replacement matches the thermal characteristics and pin configuration of the original DO-204AL footprint.
