Overview
The Microsemi Corporation 1EZ200D10E3/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 200V with a tolerance of ±10%. The device has a maximum power dissipation rating of 1W and operates within a temperature range of -65°C to +150°C. It is housed in a DO-41 (DO-204AL) axial plastic package with two terminals. The component is RoHS compliant and supplied in tape and reel packaging.
Feature Summary
- Provides stable voltage regulation at 200V with ±10% tolerance
- Capable of handling up to 1W power dissipation
- Operates reliably across an extended temperature range from -65°C to +150°C
- RoHS compliant construction in a standard axial leaded package
Applications
- Voltage reference circuits requiring 200V stability
- Overvoltage protection stages in high-voltage systems
- Power supply regulation modules
- Industrial control circuitry
Procurement Notes
Verify the specific suffix 'TR8' indicates tape and reel packaging when ordering. Confirm RoHS compliance status matches project requirements, as non-compliant variants exist within the same series. Ensure the supplier provides official datasheets confirming the 1W power rating and 200V Zener voltage specifications before finalizing procurement.
Selection Notes
Select this component when a 200V Zener voltage with 10% tolerance is required. The 1W power rating suits moderate current applications. The wide operating temperature range supports harsh environments. Verify that the axial DO-41 package fits the board layout constraints compared to surface mount alternatives.
Part Context
This part belongs to the Microsemi 1EZ series of 1-watt Zener diodes. The series offers various voltage options from 110V to 200V with different tolerance suffixes. The 'E3' suffix denotes RoHS compliance, while 'TR8' specifies the tape and reel packaging format for automated assembly processes.
Replacement Considerations
Compatible substitutes include other 1W, 200V Zener diodes in the DO-41 package with similar tolerance ratings. Verify thermal characteristics and reverse leakage current specs match the original design requirements.
