1EZ200D5E3/TR8

Overview

The Microsemi Corporation 1EZ200D5E3/TR8 is a single silicon Zener diode housed in the DO-41 (DO-204AL) axial plastic package. It features a nominal Zener voltage of 200V with a tolerance of ±5% and a maximum power dissipation rating of 1W. The device operates within a temperature range of -65°C to +150°C, supports a reverse leakage current of 500nA at 144V, and exhibits a forward voltage of 1.2V at 200mA. This component is RoHS compliant and classified under ECCN code EAR99.

Feature Summary

• Provides stable voltage regulation with tight 5% tolerance across a wide operating temperature range.
• Utilizes a robust DO-41 plastic encapsulation suitable for high DC currents and full power ratings.
• Features an isolated case connection and unidirectional configuration for reliable circuit integration.

Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in electronic systems.
• General-purpose voltage regulation tasks in industrial equipment.

Procurement Notes

Verify compliance status and lead times directly with authorized distributors or Microsemi representatives. Confirm that the specific suffix matches the required RoHS standards and packaging format. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes before finalizing acquisition.

Selection Notes

Select this component when a 200V Zener voltage with 5% precision is required in a standard axial package. Consider the 1W power rating and thermal management needs for continuous operation. Evaluate the -65°C to +150°C temperature range against environmental conditions. Compare alternative tolerances if tighter voltage stability is necessary for the specific application design.

Part Context

This part belongs to the Microsemi 1EZ series of 1-watt silicon Zener diodes. The series offers various voltage options from 110V to 200V with different tolerance suffixes. The 'E3' suffix indicates RoHS compliance, while '/TR8' specifies the tape and reel packaging format for automated assembly processes.

Replacement Considerations

Check for direct equivalents such as the 1EZ200D5 variant, noting differences in RoHS compliance and packaging. Verify that any substitute maintains the 200V Zener voltage, 1W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility without redesigning the circuit board.
