1EZ150D5E3/TR8

Overview

The 1EZ150D5E3/TR8 is a single silicon Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 150 V with a tolerance of ±5%. The device has a maximum power dissipation rating of 1 W and is housed in an axial-lead DO-204AL (DO-41) plastic package. It is supplied in tape and reel packaging for automated assembly.

Feature Summary

• Provides precise voltage regulation with tight ±5% tolerance
• Utilizes standard axial-lead DO-41 plastic encapsulation
• Designed for high DC current operation at full power rating

Applications

• Voltage reference circuits
• Overvoltage protection
• General purpose voltage regulation

Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance and 'TR8' denotes tape and reel packaging. Confirm the manufacturer as Microsemi Corporation or its successor entity, Microchip Technology, to ensure component authenticity and traceability before procurement.

Selection Notes

Select this component when a 150 V Zener voltage with 5% precision is required in a 1 W axial package. Ensure the application supports the thermal requirements for full-power operation. Verify that the tape and reel format aligns with the manufacturing assembly equipment specifications.

Part Context

This part belongs to the 1EZ series of 1 Watt Zener Diodes from Microsemi. The series offers various voltage selections within the DO-41 package. The 'E3' suffix typically signifies RoHS compliance, while 'TR8' specifies the reel quantity and packaging method for surface mount or through-hole automated insertion.

Replacement Considerations

Consult official Microchip/Microsemi documentation for verified cross-reference data. Generic equivalents may match electrical parameters but often differ in screening levels or reliability standards. No specific substitute part numbers are confirmed in the provided source material.
