1EZ200D5/TR12

Overview

The Microsemi Corporation 1EZ200D5/TR12 is a single axial-leaded silicon Zener diode housed in a DO-41 plastic package. It provides voltage regulation with a nominal Zener voltage of 200 V and a maximum power dissipation rating of 1.0 W. The component features a standard voltage tolerance of ±5%, indicated by the 'D' suffix, and operates within a temperature range of -65°C to +150°C. It is supplied in tape and reel packaging for automated assembly processes.

Feature Summary

• Provides stable voltage regulation across a wide operating temperature range suitable for demanding environments.
• Utilizes a hermetically sealed plastic encapsulation design for reliable performance.
• Offers standardized voltage tolerances through specific alphanumeric suffix identification.

Applications

• High-voltage reference circuits requiring precise regulation.
• Overvoltage protection stages in industrial electronic systems.
• Voltage clamping applications in high-reliability aerospace equipment.

Procurement Notes

Verify compliance requirements before procurement as this specific part number may not meet current RoHS standards compared to e3 variants. Confirm that the standard ±5% tolerance aligns with circuit specifications. Ensure the DO-41 axial leaded package fits the designated PCB footprint and that the 1.0 W power rating accommodates thermal management constraints within the final assembly.

Selection Notes

Select this component when a 200 V regulation point is required with moderate precision. Consider the 1EZ200D2 or 1EZ200D1 if tighter voltage tolerances are necessary. Evaluate the 2EZ200D5 series if higher power dissipation capabilities are needed for the application environment.

Part Context

This device belongs to the Microsemi 1EZ series of 1.0 Watt Zener diodes. The series covers a broad voltage spectrum from 110 V to 200 V in the DO-41 package. These components are designed for general-purpose voltage regulation and are often utilized in military and aerospace sectors where long-term reliability is critical.

Replacement Considerations

Public confirmed substitute part numbers: 1EZ200D5, 1EZ200D2, 1EZ200D1, 2EZ200D5.
