Overview
The 1EZ150D5/TR8 is a single Zener diode manufactured by Microsemi Corporation, designed for through-hole mounting in the DO-204AL (DO-41) axial package. It features a nominal Zener voltage of 150 V with a tolerance of ±20% and a maximum power dissipation of 1 W. The device operates within a temperature range of -65°C to 150°C and includes a forward voltage of 1.2 V at 200 mA. Supplied in tape and reel packaging, it serves as a robust voltage reference component.
Feature Summary
- Provides stable voltage regulation via Zener breakdown characteristics
- Supports high-temperature operation up to 150°C
- Utilizes axial leaded construction for reliable through-hole integration
Applications
- Voltage reference circuits requiring 150 V stabilization
- Overvoltage protection stages in industrial equipment
- Power supply regulation modules
Procurement Notes
Verify the specific suffix TR8 indicates tape and reel packaging configuration. Confirm the manufacturer designation remains Microsemi Corporation or its successor entity. Ensure the DO-204AL package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a 150 V Zener voltage with 1 W power rating is required. The ±20% tolerance suits applications where precise voltage accuracy is not critical. Consider the axial package form factor for manual assembly or standard through-hole manufacturing processes.
Part Context
This part belongs to the Microsemi single Zener diode family, specifically the 1EZ series characterized by 1 W power dissipation. It shares the DO-204AL package with other variants in the lineup but differs in voltage ratings and tolerance specifications compared to higher-power models like the 3EZ series.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent 150 V 1 W Zener diodes from other manufacturers based on electrical parameters and package dimensions.
