1EZ200D2/TR12

Overview

The 1EZ200D2/TR12 is a single Zener diode manufactured by Microsemi Corporation, designed for voltage regulation applications. It features a nominal Zener voltage of 200 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and utilizes the DO-204AL (DO-41) axial through-hole package. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides precise voltage regulation with a 2% tolerance on the 200 V Zener voltage.
• Capable of handling high DC currents and full power ratings when adequate heat sinking is provided.
• Constructed using silicon technology in an isolated axial leaded package.

Applications

• Voltage reference circuits requiring stable 200 V levels
• Overvoltage protection in industrial equipment
• Power supply regulation modules

Procurement Notes

Verify component authenticity against Microsemi specifications due to potential availability from third-party distributors. Confirm package integrity and lead condition upon receipt. Ensure storage conditions maintain moisture sensitivity level 1 compliance. Cross-reference datasheet revisions to confirm parameter consistency before integration into final designs.

Selection Notes

Select this component when a 200 V Zener voltage with high precision (±2%) is required in a through-hole configuration. Consider the 1 W power rating and thermal management needs for continuous operation. The DO-204AL package suits standard PCB mounting techniques. Evaluate if tighter tolerances or different power ratings are necessary for specific circuit constraints.

Part Context

This part belongs to the Microsemi Commercial Components Group discrete semiconductor product line, specifically the single Zener diode category. It is related to other variants in the EZ series, such as the 1EZ100D and 3EZ series, which offer different voltage ratings and power capabilities while maintaining similar axial packaging standards for legacy and robust electronic systems.

Replacement Considerations

Direct substitutes include other 200 V, 1 W Zener diodes in DO-204AL packages with comparable ±2% tolerance. Verify electrical parameters such as impedance and leakage current match the original design requirements. Check pinout compatibility and thermal characteristics to ensure seamless integration without circuit modification.
