1EZ150D/TR12

Overview

The 1EZ150D/TR12 is a silicon Zener diode manufactured by Microsemi Corporation, designed for voltage regulation 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 a DO-204AL (DO-41) axial-leaded plastic package. It supports through-hole mounting and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation in the 150 V range
• Capable of handling full power ratings with adequate heat sinking
• Constructed with moisture classification Level 1 requiring no dry pack

Applications

• Voltage regulation circuits
• High reliability screening levels
• General purpose discrete semiconductor applications

Procurement Notes

Verify component authenticity against official Microsemi documentation before integration. Confirm that the specific suffix matches the required tolerance and packaging specifications. Ensure compliance with project environmental standards as this variant may not meet RoHS requirements. Validate thermal management capabilities for continuous operation at rated power.

Selection Notes

Select this component when a 150 V Zener reference with standard 20% tolerance is required. The DO-204AL package suits through-hole designs needing robust mechanical stability. Consider thermal derating if ambient temperatures approach the upper operational limit. Verify availability of military equivalent screening if higher reliability is mandated for the application environment.

Part Context

This part belongs to the 1EZ series of 1 Watt Zener Diodes produced by Microsemi's Scottsdale Division. The series offers various voltage selections from 110 to 200 volts in a DO-41 plastic package. Different suffixes indicate varying voltage tolerances, allowing designers to choose precision or standard options based on circuit requirements.

Replacement Considerations

Consult Microsemi for verified substitutes such as other 1EZ series variants with adjusted voltage or tolerance suffixes. Cross-reference JEDEC equivalents like the 1N59xx series for glass-encapsulated alternatives if hermetic sealing is preferred over plastic construction.
