1EZ150D/TR8

Overview

The Microsemi Corporation 1EZ150D/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 150 V with a tolerance of ±2%. The device is rated for a maximum power dissipation of 3 W and utilizes the DO-204AL (DO-41) axial leaded plastic package. It supports through-hole mounting and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides precise voltage regulation with tight ±2% tolerance at 150 V
• Capable of handling high power dissipation up to 3 W in a standard axial package
• Engineered for reliable operation across extreme industrial temperature ranges

Applications

• High-voltage DC power supply regulation circuits
• Overvoltage protection stages in industrial control systems
• Reference voltage generation in precision measurement equipment

Procurement Notes

Verify component authenticity and datasheet alignment before integration, as this part may be subject to end-of-life status or manufacturing changes. Confirm that the specific suffix indicates the correct tolerance and packaging configuration required for your design. Ensure compliance with relevant environmental regulations applicable to your region prior to procurement.

Selection Notes

Select this component when a stable 150 V reference is required with strict tolerance limits. The 3 W power rating allows for robust performance in high-current scenarios compared to lower-wattage alternatives. The DO-41 package facilitates easy integration into existing through-hole PCB layouts without requiring specialized surface-mount assembly processes.

Part Context

This component belongs to the Microsemi 3EZ series of high-power Zener diodes. These devices are engineered for demanding environments where stability and durability are critical. The series offers various voltage options within the same physical footprint, allowing designers to maintain consistent board layouts while adjusting voltage specifications.

Replacement Considerations

Check for direct equivalents from Microsemi or other manufacturers offering identical 150 V, 3 W, ±2% specifications in the DO-41 package. Verify thermal characteristics and reverse leakage current parameters to ensure functional compatibility in the target circuit.
