3EZ190DE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 3EZ190DE3/TR12 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 190 V with a maximum power dissipation rating of 3 W. The device utilizes a DO-204AL (DO-41) axial leaded package suitable for through-hole mounting. Electrical characteristics include a reverse leakage current of 500 nA at 144.8 V and a forward voltage drop of 1.2 V at 200 mA. The component operates within a temperature range of -65°C to +150°C and carries an MSL rating of 1.

Single Zener Diodes Feature Summary

Provides stable voltage regulation across broad operating current and temperature ranges
Features flexible axial-lead mounting terminals for reliable through-hole integration
Withstands high surge stresses during transient events

Single Zener Diodes Applications

Voltage regulation in industrial control systems
Overvoltage protection circuits
Reference voltage generation in measurement equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' indicates RoHS compliance status as per manufacturer documentation. Confirm the 'TR12' designation corresponds to the required tape and reel packaging quantity. Ensure the DO-204AL package dimensions match the target PCB layout constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 190 V regulation point is required with a 3 W power handling capability. The DO-204AL package offers robust mechanical stability compared to smaller surface-mount alternatives. Consider the wide operating temperature range for environments subject to significant thermal fluctuations.

Single Zener Diodes Part Context

This part belongs to the 3EZ series of silicon Zener diodes manufactured by Microsemi Corporation.
