Overview
The 1EZ150D2E3/TR8 is a single Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 150 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and is housed in a DO-204AL (DO-41) axial through-hole package. It is supplied in tape and reel packaging, designated by the /TR8 suffix. This component is designed for general-purpose voltage regulation and protection applications requiring stable reference voltages.
Feature Summary
- Provides precise voltage regulation with ±2% tolerance
- Rated for 1 W power dissipation in axial leaded package
- Suitable for through-hole mounting on printed circuit boards
Applications
- Voltage reference circuits
- Overvoltage protection stages
- Power supply regulation modules
Procurement Notes
Verify the exact part number including the /TR8 suffix to ensure correct tape and reel packaging configuration. Confirm RoHS compliance status as indicated by the E3 suffix in official datasheets. Check current product status, as availability may vary due to lifecycle changes. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a 150 V Zener voltage with high precision is required in a through-hole assembly. Compare against higher power variants like the 2W or 3W series if thermal management allows. Consider the ±2% tolerance requirement versus standard 5% or 10% options. Verify package compatibility with existing PCB footprints before finalizing the design choice.
Part Context
This part belongs to the Microsemi single Zener diode family, specifically the 1EZ series which denotes 1 W power rating. The E3 suffix typically indicates RoHS compliance. It shares the DO-204AL package form factor with other axial diodes in the lineup, allowing for similar mechanical integration while differing in electrical specifications such as voltage and tolerance.
Replacement Considerations
Direct substitutes include the 1EZ150D2/TR8 (non-RoHS version) or the 1EZ150D5E3/TR8 (±5% tolerance). For higher power needs, consider the 2EZ150D2E3/TR8 (2 W) or 3EZ150D2E3/TR8 (3 W) within the same voltage class.
