1EZ170D5E3/TR8

Overview

The Microsemi Corporation 1EZ170D5E3/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 170 V with a tolerance of ±5% and a maximum power dissipation rating of 1 W. The component utilizes an axial-lead DO-204AL (DO-41) plastic package, providing two terminals for through-hole mounting. This specific variant is RoHS compliant and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation at a nominal 170 V level
• Features a 1 W power dissipation capability for high-current operation
• Utilizes a standard DO-41 axial leaded plastic package
• Compliant with RoHS environmental standards

Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection in electronic systems
• General-purpose voltage clamping applications

Procurement Notes

Verify the exact suffix configuration against official Microsemi documentation to confirm RoHS compliance status and packaging type. Confirm that the TR8 designation corresponds to the required tape and reel quantity. Ensure the component meets all necessary environmental and export control classifications for your specific deployment region before finalizing procurement.

Selection Notes

Select this component when a 170 V Zener voltage with tight 5% tolerance is required in a 1 W power class. The DO-41 package is suitable for through-hole assembly processes. Consider the operating temperature range and thermal management requirements if the device will be operated near its maximum power dissipation limits in enclosed environments.

Part Context

This part belongs to the Microsemi 1EZ series of axial-leaded Zener diodes. The series offers various voltage selections from 110 V to 200 V in a DO-41 plastic package. Variants are available with different tolerance levels and screening grades, including military equivalents, allowing for flexible selection based on precision and reliability requirements.

Replacement Considerations

Cross-reference with other 170 V, 1 W Zener diodes in the DO-41 package. Verify electrical parameters such as impedance and leakage current match the original design specifications. Check for equivalent RoHS compliance and package dimensions to ensure mechanical compatibility.
