2EZ4.7D10E3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 2EZ4.7D10E3/TR8 is a single Zener diode with a nominal voltage of 4.7 V and a maximum power dissipation of 2 W. It features a ±10% tolerance and utilizes a DO-204AL (DO-41) axial through-hole package. The device operates within a temperature range of -65°C to 150°C and has a maximum impedance of 9 Ohms.

Single Zener Diodes Feature Summary

• Provides robust voltage regulation for circuits requiring higher energy absorption capabilities than standard low-power devices.

Single Zener Diodes Applications

• Protection of Electronic Control Unit (ECU) inputs against transient voltage events.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR8' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as per current manufacturer documentation, noting that older stock may differ. Ensure the DO-204AL package matches your PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V reference or clamp is needed with 2 W surge handling capacity. The axial leaded format suits manual assembly or high-reliability applications where surface mount options are unsuitable. Verify the ±10% tolerance meets circuit precision requirements.

Single Zener Diodes Part Context

This part belongs to the 2EZ series of axial-leaded Zener diodes from Microsemi. These components are designed for general-purpose voltage regulation and protection in industrial and automotive environments, offering higher power ratings than common 500 mW variants.
