Overview
The 1EZ150DE3/TR12 is a single Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 150 V and a power dissipation rating of 1 W. The device utilizes a DO-204AL (DO-41) axial through-hole package. Electrical characteristics include a maximum reverse leakage current of 500 nA at 130.4 V and a forward voltage drop of 1.2 V at 200 mA. The component is RoHS compliant and lead-free.
Feature Summary
- Provides stable voltage regulation with a 150 V nominal breakdown voltage
- Constructed in a durable glass-encapsulated axial leaded package for through-hole mounting
- Designed to withstand high surge stresses typical in power applications
Applications
- Voltage regulation circuits requiring 150 V reference
- Overvoltage protection stages
- Clamping applications in electronic systems
Procurement Notes
Verify the specific suffix TR12 indicates tape and reel packaging when sourcing. Confirm RoHS compliance status matches project requirements. Ensure the DO-204AL package dimensions align with PCB layout constraints. Cross-reference the manufacturer part number with official Microsemi documentation to confirm availability and revision status before procurement.
Selection Notes
Select this component for applications requiring a 150 V Zener voltage with 1 W power handling. The DO-204AL package suits through-hole assembly processes. Consider the ±20% tolerance if precise voltage regulation is not critical. Evaluate thermal management needs based on the junction-to-ambient thermal resistance specifications provided in the datasheet.
Part Context
This part belongs to the Microsemi 1EZ series of single Zener diodes. These components are designed for general-purpose voltage regulation and protection. The series offers various voltage ratings within a standard axial leaded form factor, ensuring compatibility with existing through-hole manufacturing infrastructure.
Replacement Considerations
Equivalent parts from other manufacturers may be considered if they match the 150 V Zener voltage, 1 W power rating, and DO-204AL package. Verify electrical parameters such as leakage current and forward voltage to ensure functional compatibility.
