1EZ200DE3/TR12

Overview

The 1EZ200DE3/TR12 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 has a maximum power dissipation rating of 1 W and operates within a junction temperature range of -65°C to +150°C. It utilizes a DO-41 (DO-204AL) axial-leaded plastic package for through-hole mounting. The component exhibits a reverse leakage current of 500 nA at 152 V and a forward voltage drop of 1.2 V at 200 mA.

Feature Summary

• Provides stable voltage regulation across broad operating currents and temperature ranges
• Features flexible axial-lead terminals suitable for through-hole mounting applications
• Encapsulated in moisture-resistant plastic material classified as Level 1

Applications

• Voltage regulation circuits requiring high-voltage stability
• Protection against overvoltage conditions in electronic systems
• Reference voltage sources in precision measurement equipment

Procurement Notes

Verify the specific suffix 'e3' confirms lead-free matte tin plating compliance. Confirm the 'TR12' designation indicates reel packaging specifications. Ensure the manufacturer source is Microsemi or authorized successor entities due to corporate acquisitions. Validate that the component meets required environmental standards for the intended deployment environment.

Selection Notes

Select this component when a 200 V Zener voltage with 5% tolerance is required in a standard axial package. Consider the 1 W power rating and thermal management needs for continuous operation. Evaluate the ±5% tolerance against circuit sensitivity requirements compared to tighter tolerance alternatives.

Part Context

This part belongs to the 1EZ series of 1.0 watt Zener diodes produced by Microsemi. The series offers voltage selections from 110 to 200 volts in DO-41 plastic packages. The 'e3' suffix denotes RoHS compliance, while the base model provides standard military-grade screening levels without dry pack requirements.

Replacement Considerations

Compatible substitutes include other 1W Zener diodes with 200V nominal voltage and ±5% tolerance in DO-41 packages. Verify equivalent thermal resistance and leakage current specifications before substitution.
