1EZ160DE3/TR8

Overview

The 1EZ160DE3/TR8 is a single Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 160 V with a tolerance of ±20%. The device has a maximum power dissipation of 1 W and utilizes a DO-204AL (DO-41) axial through-hole package. It operates within a temperature range of -65°C to 150°C.

Feature Summary

• Provides stable voltage regulation at 160 V for circuit protection applications
• Designed for through-hole mounting in standard DO-204AL packages
• Capable of operating across an extended industrial temperature range

Applications

• Voltage reference circuits requiring 160 V stabilization
• Overvoltage protection in electronic systems
• Clamping applications in high-voltage signal paths

Procurement Notes

Verify the exact suffix configuration against official Microsemi documentation, as variations such as TR12 or D2 may indicate different packaging or tolerance specifications. Confirm RoHS compliance status directly from the manufacturer's current product change notices, as historical data indicates potential non-compliance for similar legacy parts. Ensure the component matches the required axial lead form factor for your assembly process.

Selection Notes

Select this component when a 160 V Zener voltage with 1 W power handling is required in a through-hole format. The ±20% tolerance makes it suitable for general-purpose regulation rather than precision references. Consider the DO-204AL package size constraints and thermal management requirements for continuous operation at elevated temperatures.

Part Context

This part belongs to the Microsemi single Zener diode family, specifically designed for robust voltage control in discrete semiconductor applications. The 1EZ series typically offers reliable performance in standard axial packages, serving as a fundamental component for basic voltage clamping and reference tasks in industrial and commercial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with equivalent 160 V, 1 W Zener diodes from other manufacturers based on pinout and electrical characteristics.
