2EZ160DE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 2EZ160DE3/TR12 is a silicon axial-leaded Zener diode rated for 2.0 watts of steady-state power dissipation at lead temperatures below 60°C. It provides a nominal Zener voltage of 160 V with a standard tolerance of ±5%. The device operates within an ambient temperature range of -65°C to +150°C and features a maximum reverse current of 6500 µA when measured at 121.6 V. Its maximum Zener impedance is 650 Ohms, and it withstands a non-recurrent peak surge current of 11 A.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and is nonsensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in electronic circuits requiring high reliability
• Protection against transient overvoltage events
• Reference voltage sources in industrial equipment

Single Zener Diodes Procurement Notes

Verify the component's authenticity by checking the manufacturer's marking and datasheet specifications. Confirm that the RoHS compliant 'e3' suffix matches the required plating type. Ensure the tape and reel 'TR' suffix aligns with automated assembly requirements. Cross-reference the part number with official Microsemi documentation to confirm availability and screening levels before procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 160 V Zener voltage with ±5% tolerance. Consider its 2-watt power rating and thermal resistance characteristics for heat dissipation needs. Verify compatibility with the DO-41 plastic package dimensions. Evaluate the maximum surge current capability against expected transient conditions in the target circuit design.

Single Zener Diodes Part Context

This component belongs to the 2EZ series of 2.0 watt Zener diodes manufactured by Microsemi Corporation. The series offers a wide selection of voltages from 3.6 V to 200 V in a DO-41 plastic package. The 'e3' suffix indicates RoHS compliance, while the 'TR' suffix denotes tape and reel packaging for automated processing.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 2-watt Zener diodes with a 160 V nominal voltage and similar tolerance ratings. Surface mount equivalents such as SMBJ2EZ160D5 are available in the DO-214AA package. Verify electrical parameters and physical dimensions before substitution.
