Overview
The Microsemi Corporation 1EZ200D2E3/TR8 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 200V with a tight tolerance of 2%. The device is rated for a maximum power dissipation of 1W and operates within an extended temperature range from -65°C to 150°C. It utilizes the DO-204AL (DO-41) axial leaded plastic package, ensuring compatibility with standard through-hole mounting processes. The component is RoHS compliant and marked as unidirectional.
Feature Summary
- Provides precise voltage regulation with a 2% tolerance at 200V
- Operates reliably across an extended industrial temperature range
- Utilizes a robust DO-204AL axial leaded plastic package
Applications
- Precision voltage reference circuits
- Over-voltage protection in electronic systems
- Voltage clamping applications
Procurement Notes
Verify the specific suffix 'TR8' indicates tape-and-reel packaging when sourcing. Confirm that the 'E3' designation ensures compliance with current environmental standards. Cross-reference the manufacturer's latest documentation to ensure the part remains active and available for production.
Selection Notes
Select this component when a stable 200V reference with high precision is required. The 1W power rating suits moderate current applications. Ensure the circuit design accommodates the thermal characteristics of the DO-41 package for reliable long-term operation under load.
Part Context
This part belongs to the Microsemi 1EZ series of axial-leaded Zener diodes. The series offers various voltage options and tolerance levels, including 1%, 2%, 5%, and 10%. The 1EZ variant specifically denotes a 1W power rating, distinguishing it from higher or lower power counterparts in the broader product family.
Replacement Considerations
Compatible substitutes include other 200V Zener diodes with 1W power ratings and 2% tolerance in the DO-41 package. Verify electrical parameters such as impedance and leakage current match the original specifications before implementation.
