1EZ170D5E3/TR12

Overview

The Microsemi Corporation 1EZ170D5E3/TR12 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 170 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 1.0 W and utilizes the DO-41 axial leaded plastic package. This component is RoHS compliant, indicated by the e3 suffix, and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation with a 170 V nominal breakdown voltage
• Encapsulated in a durable DO-41 plastic axial leaded package
• Capable of operating at full power rating with adequate heat sinking

Applications

• Voltage regulation circuits
• Protection of voltage-sensitive electronic devices
• General purpose discrete semiconductor applications

Procurement Notes

Verify the specific suffix 'e3' confirms RoHS compliance status. Confirm the 'TR12' designation indicates tape and reel packaging. Ensure the part number matches the exact 170 V specification required for the design. Check for any military equivalent screening levels if higher reliability is needed.

Selection Notes

Select this component when a 170 V Zener voltage is required in an axial leaded format. The 1.0 W power rating suits moderate current applications. Consider the ±5% tolerance for standard regulation needs. Verify thermal management requirements for continuous operation at full power.

Part Context
