1EZ100D2E3/TR8

Overview

The Microsemi Corporation 1EZ100D2E3/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and operates within an extended temperature range from -65°C to 150°C. Housed in the DO-204AL (DO-41) axial leaded plastic package, it supports through-hole mounting. This component is supplied in tape and reel packaging for automated assembly processes.

Feature Summary

• Provides precise voltage regulation with a 100 V nominal breakdown voltage and ±2% tolerance.
• Capable of handling a maximum power dissipation of 1 W for stable operation under load.
• Engineered for reliable performance across a wide operating temperature range from -65°C to 150°C.
• Utilizes a standard DO-204AL axial leaded package suitable for through-hole circuit board integration.

Applications

• Precision voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in sensitive electronic systems
• Voltage clamping applications in signal conditioning paths

Procurement Notes

Verify the specific suffix E3 confirms lead-free compliance status against current manufacturer specifications. Confirm the TR8 designation matches the required tape and reel quantity for your production line. Ensure the DO-204AL package dimensions align with your PCB footprint requirements. Cross-reference the part number with the latest Microsemi or Microchip datasheet to confirm active status and any recent design changes.

Selection Notes

Select this component when a 100 V Zener voltage with high precision is required. The ±2% tolerance makes it suitable for applications where tighter regulation than standard 5% parts is necessary. Consider the 1 W power rating for thermal management needs. The axial leaded format is ideal for prototyping or low-volume through-hole designs rather than surface mount constraints.

Part Context

This part belongs to the 1EZ series of Zener diodes manufactured by Microsemi Corporation, now part of Microchip Technology. The series offers various voltage options in the DO-204AL package. The '1EZ' prefix typically denotes a 1 W power rating variant within the broader Zener diode portfolio. These components are widely used in industrial and commercial electronics for basic voltage regulation tasks.

Replacement Considerations

Check for direct equivalents such as the 1EZ100D5/TR8 if a 5% tolerance is acceptable. Verify compatibility with other manufacturers offering 100 V, 1 W Zener diodes in the DO-41 package. Ensure any substitute maintains the same ±2% tolerance and temperature range specifications.
