Overview
The 1EZ200D2/TR8 is a single Zener diode manufactured by Microsemi Corporation, designed for through-hole mounting in DO-204AL (DO-41) axial packages. It features a nominal Zener voltage of 200 V with a tight tolerance of ±2% and a maximum power dissipation of 1 W. The device exhibits a maximum reverse leakage current of 500 nA at 152 V and a forward voltage drop of 1.2 V at 200 mA. Operating temperatures range from -65°C to 150°C, with a maximum impedance of 1900 Ohms.
Feature Summary
- Provides precise voltage regulation with a ±2% tolerance on the 200 V Zener voltage.
- Engineered for high-temperature reliability with an operating range extending to 150°C.
- Utilizes a standard DO-204AL axial leaded package for robust through-hole integration.
Applications
- Precision voltage reference circuits requiring stable 200 V levels
- Overvoltage protection stages in industrial control systems
- Clamping applications in high-voltage signal processing paths
Procurement Notes
Verify component authenticity due to discontinuation status. Confirm package integrity and lead condition upon receipt. Ensure storage conditions maintain moisture sensitivity level 1 compliance. Cross-reference datasheet revisions for any parameter updates prior to final design validation.
Selection Notes
Select this component when a highly accurate 200 V reference is required within a standard axial package. Consider the ±2% tolerance against circuit precision needs. Evaluate thermal management requirements given the 1 W power rating and 150°C junction temperature limit for long-term stability.
Part Context
This part belongs to Microsemi's 1EZ series of single Zener diodes, which are characterized by high accuracy and reliability for demanding electronic applications. The series offers various voltage options in the DO-204AL package, catering to diverse voltage regulation and protection requirements across industrial and commercial sectors.
Replacement Considerations
Potential substitutes include the 1EZ200D2/TR12 variant, which shares identical electrical specifications but utilizes tape-and-reel packaging instead of bulk. Verify pinout compatibility and thermal characteristics before implementation.
