1EZ160D2/TR8

Overview

The Microsemi Corporation 1EZ160D2/TR8 is a silicon Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 160V with a tight tolerance of ±2%. The component is rated for a maximum power dissipation of 1W and utilizes the DO-204AL (DO-41) axial through-hole package. It operates within an extended temperature range from -65°C to +150°C, ensuring reliability in demanding environments.

Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance on the 160V breakdown voltage.
• Engineered for high thermal stability and reliable operation across a wide industrial temperature range.
• Constructed using robust silicon technology housed in a standard axial leaded package for easy integration.

Applications

• Precision voltage reference circuits requiring stable high-voltage sources.
• Overvoltage protection stages in power supply input lines.
• Clamping applications in high-voltage signal processing paths.

Procurement Notes

Verify the specific suffix 'D2' against official Microsemi documentation to confirm the exact ±2% tolerance grade, as generic listings may not distinguish it from wider tolerance variants. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical data indicates potential variations in environmental compliance for this series. Ensure the DO-204AL package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a stable 160V reference is required with tighter accuracy than standard ±5% or ±10% Zener diodes offer. The 1W power rating allows for moderate current handling in continuous operation. Consider the axial DO-204AL package if manual insertion or specific through-hole mounting constraints are present. Evaluate the reverse leakage characteristics at elevated temperatures if the application involves significant thermal stress.

Part Context

This part belongs to the Microsemi 1EZ series of general-purpose Zener diodes. These components are widely used in industrial and commercial electronics for basic voltage regulation tasks. The 1EZ series typically offers a broad range of voltage values in the same standardized package, allowing designers to maintain consistent mechanical layouts while adjusting electrical specifications.
