Overview
The Microsemi Corporation 1EZ150D2/TR12 is a single Zener diode designed for through-hole mounting in the DO-204AL (DO-41) axial package. It features a nominal Zener voltage of 150 V with a tight tolerance of ±2%. The device supports a maximum power dissipation of 1 W and operates within a junction temperature range of -65°C to 175°C. Reverse leakage current is specified at 500 nA when tested at 114 V. This component is manufactured by Microsemi Corporation, which is part of Microchip Technology.
Feature Summary
- High precision voltage regulation with ±2% tolerance
- Robust thermal performance suitable for high-temperature environments
- Standard axial leaded construction for reliable through-hole integration
Applications
- Precision voltage reference circuits
- Overvoltage protection stages
- Clamping applications in power supplies
Procurement Notes
Verify the specific suffix D2 against official Microchip documentation to confirm the ±2% tolerance variant. Confirm RoHS compliance status as historical records indicate potential variations. Ensure the DO-204AL package matches your PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when precise voltage clamping is required without the need for external trimming. The ±2% tolerance distinguishes it from standard ±5% or ±10% variants. Consider the 1 W power rating and thermal resistance when designing heat dissipation strategies for continuous operation.
Part Context
This part belongs to the 1EZ series of single Zener diodes produced by Microsemi Corporation. The series offers various voltage ratings and tolerance levels. The TR12 suffix indicates tape and reel packaging, facilitating automated assembly processes in high-volume manufacturing environments.
Replacement Considerations
Check for the 1EZ150D2E3/TR12 variant if lead-free compliance is strictly required. Verify that substitute parts maintain the same ±2% tolerance and DO-204AL package dimensions to ensure mechanical and electrical compatibility.
