1EZ200DE3/TR8

Overview

The 1EZ200DE3/TR8 is a single silicon Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 200 V with a tolerance of ±20%. The device has a maximum power dissipation rating of 2 W and is housed in an axial-lead DO-204AL (DO-41) plastic package. It supports through-hole mounting and operates within a temperature range of -65°C to 150°C.

Feature Summary

• Provides voltage regulation capabilities using a single unidirectional silicon junction.
• Encapsulated in a standard DO-41 plastic body for robust axial leaded integration.
• Compliant with RoHS directives, indicating restricted hazardous substance management.

Applications

• Voltage reference circuits requiring stable high-voltage regulation.
• Overvoltage protection stages in electronic systems.
• General-purpose discrete semiconductor applications.

Procurement Notes

Verify the specific suffix 'TR8' against current manufacturer documentation to confirm tape-and-reel packaging specifications. Confirm that the component remains active or check for official end-of-life notices, as availability may be limited. Ensure the selected variant matches the required 200V Zener voltage and 2W power rating for the intended design.

Selection Notes

Select this component when a 200V Zener voltage with wide tolerance is acceptable. The DO-41 package suits through-hole designs where space constraints are minimal. Consider the 2W power rating for thermal management requirements. Verify compatibility with operating temperatures up to 150°C if used in high-heat environments.

Part Context

This part belongs to the Microsemi 1EZ series of axial-leaded Zener diodes. These components are designed for general voltage regulation tasks. The series offers various voltage options within the same physical footprint, allowing for standardized inventory management across different circuit designs requiring similar mechanical interfaces.

Replacement Considerations

Consult Microsemi documentation for direct equivalents. Other parts in the 1EZ series with matching voltage and power ratings may serve as substitutes. Verify package compatibility and electrical characteristics before substitution.
