1EZ150D5/TR12

Overview

The Microsemi Corporation 1EZ150D5/TR12 is a silicon Zener diode with a nominal voltage of 150 V and a maximum power dissipation of 1 W. It features a ±5% voltage tolerance and utilizes a DO-41 axial leaded plastic package for through-hole mounting. The device operates within a junction temperature range of -65°C to +150°C, offering reliable voltage regulation in standard electronic circuits.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for easy integration into printed circuit boards
• Withstands high surge stresses during transient events

Applications

• General-purpose voltage regulation in power supply circuits
• Protection against overvoltage conditions in sensitive electronics
• Reference voltage generation in measurement and control systems

Procurement Notes

Verify the specific suffix D5 confirms the 5% tolerance requirement before procurement. Confirm that the TR12 designation matches the required reel packaging format for automated assembly processes. Ensure compatibility with existing thermal management strategies given the 1 W power rating.

Selection Notes

Select this component when a 150 V reference is needed with moderate precision. Consider the DO-41 package size constraints for board layout. Evaluate if the 1 W power rating suffices for the expected load current without excessive heat sinking requirements compared to higher wattage alternatives.

Part Context

This part belongs to the 1EZ series of 1 Watt Zener Diodes manufactured by Microsemi. The series offers various voltage selections from 110 to 200 volts with different tolerance options identified by suffixes. These plastic encapsulated devices are designed for general commercial applications requiring reliable axial-leaded components.

Replacement Considerations

Check for equivalent parts in the 1N59xx or 1EZxx series from other manufacturers that match the 150 V, 1 W, and DO-41 specifications. Verify pinout compatibility and thermal characteristics before substitution.
