1EZ150D2/TR8

Overview

The Microsemi Corporation 1EZ150D2/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 150 V with a tight tolerance of ±2%. The component is rated for a maximum power dissipation of 3 W and utilizes the DO-204AL (DO-41) axial through-hole package. It operates within a temperature range of -65°C to +150°C, ensuring stability in demanding environments.

Feature Summary

• Provides precise voltage regulation with a narrow ±2% tolerance band.
• Supports high thermal operation up to +150°C junction temperature.
• Utilizes a robust DO-204AL axial leaded package for reliable mounting.

Applications

• Precision voltage reference circuits
• Over-voltage protection stages
• Power supply regulation modules

Procurement Notes

Verify the specific suffix D2 against official Microsemi documentation to confirm the exact tolerance and packaging configuration. Confirm RoHS compliance status as historical data indicates potential non-compliance for this series. Ensure the supplier provides valid traceability for the Microsemi brand before procurement.

Selection Notes

Select this component when a stable 150 V reference is required with strict tolerance limits. The 3 W power rating allows for higher current handling compared to standard 1 W variants. Verify that the DO-204AL footprint matches the target PCB design constraints.

Part Context

This part belongs to the Microsemi 1EZ series of axial Zener diodes. These components are engineered for general-purpose voltage regulation tasks requiring reliable performance across wide temperature ranges. The series typically offers various voltage options within the same physical package form factor.

Replacement Considerations

Consult Microsemi datasheets for direct equivalents within the 1EZ series or cross-reference with other manufacturers offering 150 V, 3 W, ±2% tolerance Zener diodes in the DO-204AL package.
