• Capable of operation at high maximum DC currents with adequate heat sinking
• Features moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify the specific suffix designations carefully, as variants such as 1EZ150D2/TR12 may exhibit different compliance statuses, including RoHS non-compliance. Confirm that the E3 suffix indicates lead-free composition if required by your assembly process. Ensure the procurement source explicitly identifies the TR12 tape and reel packaging format to match automated handling requirements. Cross-reference the manufacturer part number against current availability lists due to potential lifecycle changes.

Selection Notes

Select this component when a 150 V Zener voltage with 10% tolerance is required in a standard axial package. Consider the 1 W power rating and ensure thermal management strategies are implemented for full-power operation. Verify compatibility with the operating temperature range of -65°C to +150°C. Compare against other series members like the 1EZ110D5 or 1EZ200D5 if voltage adjustments are needed while maintaining similar package constraints.

Part Context

This part belongs to the Microsemi 1EZ series of single Zener diodes, which offers various voltage selections in the DO-41 plastic package. The series typically includes options with different tolerance levels, such as 5% or 10%, catering to diverse precision requirements. These components are engineered for robust performance in axial-leaded configurations, supporting both commercial and potentially military-equivalent screening levels depending on specific ordering prefixes.

Replacement Considerations

Direct substitutes include other 150 V Zener diodes in the DO-204AL package with matching 1 W power ratings and ±10% tolerance. Verify electrical parameters such as dynamic impedance and leakage current against the original datasheet. Ensure any replacement maintains the same thermal characteristics and mounting style to fit existing board layouts without modification.
