1EZ150D10/TR12

Overview

The Microsemi Corporation 1EZ150D10/TR12 is a Zener diode with a nominal voltage of 150 V and a maximum power dissipation of 1 W. It features a tolerance of ±20% and operates within a junction temperature range of -65°C to 150°C. The device utilizes a DO-204AL (DO-41) axial through-hole package and has a maximum impedance of 1300 Ohms.

Feature Summary

• Provides stable voltage regulation at 150 V for circuit protection applications
• Designed for high-temperature operation up to 150°C junction temperature
• Utilizes a robust plastic encapsulated DO-204AL axial package

Applications

• Voltage regulation in low-power embedded designs
• General-purpose clipping and clamping circuits
• Reference voltage sources in electronic systems

Procurement Notes

Verify RoHS compliance status as the component contains lead and is non-compliant with current environmental standards. Confirm availability as distribution data indicates potential stock limitations or discontinuation risks associated with legacy Microsemi products. Ensure the specific suffix matches required packaging and screening levels.

Selection Notes

Select this component when a 150 V Zener voltage with 1 W power rating is required in an axial package. Consider the ±20% tolerance for applications not requiring tight voltage precision. Evaluate thermal management requirements given the 150°C maximum operating temperature limit and plastic package construction.

Part Context

This part belongs to the Microsemi 1EZ series of silicon Zener diodes, which are JEDEC registered equivalents to standard 1N47xx series devices. The series offers extensive voltage selection from 3.3 to 100 V, with this specific model providing 150 V regulation in a plastic DO-204AL package suitable for general industrial and commercial electronics.

Replacement Considerations

Standard replacements include the 1N5386B or 1N4746A for equivalent 150 V 5 W ratings if higher power is acceptable. For direct 1 W replacement, verify compatibility with 1N4746A or 1N5386 variants. Check manufacturer datasheets for pinout and thermal characteristics before substitution.
