1EZ160D5E3/TR8

Overview

The Microsemi Corporation 1EZ160D5E3/TR8 is a single silicon Zener diode designed for through-hole mounting in the DO-204AL (DO-41) axial leaded package. It features a nominal Zener voltage of 160 V with a tolerance of ±5% and a maximum power dissipation rating of 3 W. The device exhibits a maximum dynamic impedance of 710 Ohms and operates within a junction temperature range of -65°C to 150°C. This component is RoHS compliant and manufactured by Microsemi Corporation.

Feature Summary

• Provides stable voltage regulation with a 160 V nominal breakdown voltage
• Capable of handling up to 3 W of power dissipation in a standard axial package
• Maintains performance across an extended industrial temperature range

Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection stages in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix E3 confirms RoHS compliance status against current manufacturer documentation, as legacy stock may differ. Confirm the TR8 packaging designation matches the required reel specifications for automated assembly processes. Ensure the DO-204AL footprint aligns with existing PCB layouts before finalizing procurement orders.

Selection Notes

Select this component when a 160 V regulation point is required with moderate precision. The 3 W power rating allows for higher current handling compared to lower-power variants. The axial leaded format facilitates manual insertion or wave soldering where surface mount options are unsuitable.

Part Context

This part belongs to the Microsemi 1EZ series of high-power Zener diodes. These components are engineered for robust voltage regulation in demanding environments. The series offers various voltage options within the same physical footprint, simplifying inventory management for designs requiring different regulation levels.
