1EZ200D5/TR8

Overview

The 1EZ200D5/TR8 is a single silicon Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 200 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within a temperature range of -65°C to +150°C. It utilizes a DO-204AL (DO-41) axial leaded plastic package, providing two terminals for through-hole mounting.

Feature Summary

• Provides precise voltage regulation with tight 5% tolerance in the high-voltage range
• Operates reliably across an extended industrial temperature spectrum
• Utilizes a standard axial-leaded plastic encapsulation for robust mechanical stability

Applications

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

Procurement Notes

Verify component authenticity against Microsemi specifications due to potential availability from secondary markets. Confirm RoHS compliance status as historical data indicates non-compliance for this specific suffix variant. Ensure the DO-204AL package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a stable 200 V reference with strict 5% accuracy is required. The 1 W power rating supports moderate current loads without excessive heat sinking. Consider the axial lead form factor for manual assembly or legacy board designs requiring through-hole technology compatibility.

Part Context

This part belongs to the Microsemi 1EZ series of 1-watt Zener diodes. The series offers various voltage options within the DO-41 package. The 'D5' suffix specifically denotes the 5% tolerance grade, distinguishing it from wider tolerance variants like D10. This series is designed for general-purpose voltage regulation tasks.

Replacement Considerations

Direct substitutes include other 1W, 200V, ±5% Zener diodes in the DO-41 package from compatible manufacturers. Verify that replacement parts maintain identical thermal resistance and leakage current characteristics to ensure circuit performance parity.
