1EZ200D/TR8

Overview

The Microsemi Corporation 1EZ200D/TR8 is a single silicon Zener diode designed for through-hole mounting in DO-204AL (DO-41) axial packages. It features a nominal Zener voltage of 200 V with a tolerance of ±20% and a maximum power dissipation of 1 W. The device exhibits a maximum impedance of 1900 Ohms and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation at a nominal 200 V level
• Capable of handling 1 W power dissipation in an axial leaded package
• Engineered for reliable operation across extended industrial temperature ranges

Applications

• Voltage reference circuits requiring 200 V stabilization
• Overvoltage protection stages in high-voltage systems
• General-purpose clipping and clamping applications

Procurement Notes

Verify the specific suffix TR8 confirms tape and reel packaging when ordering. Confirm that the ±20% tolerance aligns with circuit requirements, as tighter variants exist. Ensure the DO-204AL footprint matches the target PCB design. Check current manufacturing status as component availability may vary by distributor.

Selection Notes

Select this component when a 200 V Zener reference is required in a standard axial package. The 1 W rating supports moderate current loads. Consider the 1900 Ohm impedance for dynamic regulation needs. Verify thermal management capabilities for continuous operation near the 150°C limit.

Part Context

This part belongs to the Microsemi 1EZ series of general-purpose Zener diodes. These components are widely used in power supplies and control electronics. The DO-204AL package offers robust mechanical stability for through-hole assembly processes commonly found in industrial hardware.

Replacement Considerations

Equivalent parts include the 1EZ200D10E3/TR8 and 1EZ200D2E3/TR8. Verify pinout compatibility and ensure replacement devices meet the same 200 V and 1 W specifications.
