1EZ170DE3/TR8

Overview

The Microsemi Corporation 1EZ170DE3/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 ±20%. The device is rated for a maximum power dissipation of 1 W and utilizes the DO-204AL (DO-41) axial leaded package. It supports surface mount or through-hole installation, operates within a temperature range of -65°C to 150°C, and has a moisture sensitivity level of 1.

Feature Summary

• Provides stable voltage regulation at 170 V with standard tolerance
• Capable of handling 1 W power dissipation in a compact axial package
• Operates reliably across an extended industrial temperature range

Applications

• Voltage reference circuits requiring 170 V stabilization
• Overvoltage protection in high-voltage DC systems
• Clamping applications in industrial control equipment

Procurement Notes

Verify component authenticity against Microsemi specifications due to discontinuation status. Confirm package integrity and lead condition upon receipt. Ensure storage conditions maintain MSL 1 classification. Cross-reference datasheet parameters for critical design integration. Validate supplier documentation for RoHS compliance history.

Selection Notes

Select this component when a 170 V Zener voltage is required with ±20% tolerance. The 1 W power rating suits moderate current applications. The DO-41 package allows for easy through-hole mounting. Consider thermal management for continuous operation near maximum power dissipation limits.

Part Context

This part belongs to the Microsemi 1EZ series of axial-leaded Zener diodes. The series offers various voltage options from 3.9 V to 200 V in a DO-41 plastic package. The 'E3' suffix indicates lead-free composition, while '/TR8' denotes tape and reel packaging. These components are widely used in general-purpose voltage regulation tasks.
