1EZ200D10E3/TR12

Overview

The Microsemi Corporation 1EZ200D10E3/TR12 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 200 V with a tolerance of ±10%. The device has a maximum power dissipation rating of 1.25 W and utilizes a DO-204AL (DO-41) axial leaded plastic package. It operates within a junction temperature range of -65°C to +175°C. The component is RoHS compliant and supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation at high reverse bias voltages up to 200 V
• Utilizes a rugged plastic encapsulated axial leaded package for through-hole mounting
• Operates reliably across an extended industrial temperature range

Applications

• High-voltage DC power supply regulation circuits
• Voltage reference sources for measurement instrumentation
• Overvoltage protection stages in electronic systems

Procurement Notes

Verify the specific suffix E3 confirms RoHS compliance status for your project requirements. Confirm the TR12 designation matches the required tape and reel quantity for automated assembly processes. Ensure the DO-204AL package dimensions align with your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when a precise 200 V regulation point is required with moderate power handling capabilities. The 10% tolerance suits general-purpose applications where tight precision is not critical. Consider the thermal resistance characteristics of the DO-41 package for heat dissipation planning in enclosed environments.

Part Context

This part belongs to the Microsemi 1EZ series of 1-watt and 1.25-watt Zener diodes. These devices are JEDEC registered and offer a wide selection of voltage values from low volts up to 200 V. The series is known for providing flexible axial-lead mounting terminals suitable for various standard circuit board layouts.

Replacement Considerations

Equivalent parts include the 1N5359B or other generic 200 V 1.25 W Zener diodes in DO-41 packages. Verify that substitute components meet the same 200 V nominal voltage, 10% tolerance, and 1.25 W power dissipation ratings to ensure functional compatibility.
