1EZ160DE3/TR12

Overview

The 1EZ160DE3/TR12 is a single silicon Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 160 V with a tolerance of ±5%. The device has a maximum power dissipation rating of 1.0 W and operates within a temperature range of -65°C to +150°C. It utilizes an axial-lead DO-41 (DO-204AL) plastic package for through-hole mounting. The component is RoHS compliant, indicated by the 'e3' suffix, and is supplied in a reel packaging format.

Feature Summary

• Provides stable voltage regulation at a nominal 160 V with standard 5% tolerance
• Operates reliably across a wide industrial temperature range from -65°C to +150°C
• Utilizes a durable plastic encapsulated DO-41 axial lead package

Applications

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

Procurement Notes

Verify the specific manufacturer source, as Microsemi's semiconductor division was acquired by Microchip Technology. Confirm that the 'e3' suffix denotes lead-free compliance and RoHS status. Ensure the 'TR12' designation matches the required reel quantity and packaging specifications for your assembly process. Check current availability status as older series components may be subject to discontinuation or lifecycle changes.

Selection Notes

Select this component when a 160 V Zener voltage with 5% precision is required in a 1 W power class. The DO-41 package is suitable for through-hole PCB layouts where higher thermal resistance compared to surface mount options is acceptable. Consider the operating temperature range to ensure suitability for environments exceeding standard commercial limits. Verify that the reverse leakage characteristics meet the specific circuit requirements.

Part Context

This part belongs to the 1EZ series of 1.0 watt Zener diodes produced by Microsemi. The series offers a broad selection of voltages in the DO-41 plastic package. The 'e3' suffix indicates a tin-plated terminal finish compliant with RoHS directives. This series is designed for general-purpose voltage regulation and clamping applications in various electronic equipment.

Replacement Considerations

Equivalent parts include other 160 V, 1 W Zener diodes in the DO-41 package with ±5% tolerance. Cross-reference with JEDEC registered 1N47xx series variants if voltage and power ratings align. Verify pinout compatibility and thermal performance before substitution.
