1EZ150DE3/TR8

Overview

The Microsemi Corporation 1EZ150DE3/TR8 is a single Zener diode designed for voltage regulation and protection applications. It features a nominal Zener voltage of 150 V with a tolerance of ±20%. The device has a maximum power dissipation rating of 1 W and utilizes the DO-204AL (DO-41) axial through-hole package. Key electrical characteristics include a reverse leakage current of 500 nA at 114 V and a forward voltage of 1.2 V at 1 A. The component operates within a temperature range of -65°C to 150°C.

Feature Summary

• Provides stable voltage regulation in circuits requiring a 150 V reference point.
• Capable of handling high thermal loads with an extended operating temperature range up to 150°C.
• Constructed in a robust axial through-hole package suitable for general-purpose mounting.

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify component authenticity due to potential availability from third-party distributors. Confirm RoHS compliance status as indicated by the E3 suffix, though some sources may vary. Check for end-of-life or obsolescence notices from the manufacturer before finalizing procurement plans. Ensure packaging type matches TR8 reel specifications if automated assembly is required.

Selection Notes

Select this component when a 150 V Zener voltage with ±20% tolerance is required. The 1 W power rating suits moderate current applications. Consider the DO-204AL package for through-hole implementation. Compare against higher precision variants like the 1EZ150D2 series if tighter tolerance is needed.

Part Context

This part belongs to the Microsemi single Zener diode family. It shares the same voltage rating but differs in power handling and tolerance compared to other series members. The E3 suffix typically denotes lead-free and RoHS-compliant construction, distinguishing it from older non-compliant versions.

Replacement Considerations

Direct substitutes include the 1EZ150D2E3/TR8 for tighter tolerance requirements. For lower power applications, the 1EZ150DE3/TR12 offers similar electrical characteristics in a tape-and-reel format. Verify pinout compatibility when replacing.
