1EZ200D10/TR12

Overview

The Microsemi Corporation 1EZ200D10/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 W and utilizes a DO-204AL (DO-41) axial-leaded plastic package. It operates within a temperature range of -65°C to 150°C and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation at high reverse voltages up to 200 V
• Utilizes a robust plastic encapsulated DO-41 axial leaded construction
• Capable of operation across an extended industrial temperature range

Applications

• High voltage DC power supply regulation circuits
• Overvoltage protection stages in electronic systems
• Reference voltage generation in measurement instrumentation

Procurement Notes

Verify the specific suffix 'TR12' against current manufacturer documentation to confirm tape and reel specifications, as legacy suffixes may vary. Confirm RoHS compliance status, as non-compliant variants exist within this series. Check component obsolescence status prior to procurement planning.

Selection Notes

Select this component when a precise 200 V regulation point is required with moderate power handling capabilities. Ensure the circuit design accommodates the thermal dissipation limits inherent to the 1 W rating in the DO-41 package. Verify that the ±10% tolerance aligns with the system's voltage accuracy requirements.

Part Context

This part belongs to the Microsemi 1EZ series of 1 Watt Zener diodes. The series offers a wide selection of voltage values from 110 V to 200 V in a standard DO-41 plastic package. These devices are commonly used in general-purpose electronics where reliable voltage clamping is necessary.

Replacement Considerations

Equivalent parts include the 1N5938B series or other generic 1W 200V Zener diodes in DO-41 packages. Verify electrical parameters such as impedance and leakage current match before substitution.
