The device is rated for a maximum power dissipation of 1.0 W and utilizes a DO-41 axial leaded plastic package. It operates within a junction temperature range of -65°C to +175°C and is RoHS compliant.
Feature Summary
- Provides stable voltage regulation across a wide operating current range
- Utilizes a robust plastic encapsulated DO-41 axial leaded package
- Designed for high reliability in harsh environments
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific suffix configuration against the official datasheet to ensure compatibility with required tolerance levels and environmental standards. Confirm that the RoHS compliance status aligns with project requirements, as manufacturing processes may vary by production batch. Cross-reference the part number with the manufacturer's latest obsolescence notices to ensure long-term availability.
Selection Notes
Select this component when a precise 150 V regulation point is required with standard 5% tolerance. The DO-41 package offers flexibility for through-hole mounting on printed circuit boards. Ensure the thermal management design supports the 1.0 W power rating under expected ambient conditions to maintain performance within specified limits.
Part Context
This component belongs to the 1EZ series of 1.0 watt Zener diodes manufactured by Microsemi. The series provides a broad selection of voltage options ranging from 110 V to 200 V in the same physical package. The 'e3' suffix indicates lead finish composition, while 'TR12' denotes the reel packaging format for automated assembly processes.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified equivalents. Generic replacements must match the 150 V nominal voltage, 1.0 W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility.
