1EZ130D2E3/TR12

Overview

The Microsemi Corporation 1EZ130D2E3/TR12 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 130 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-leaded plastic package. It operates within a temperature range of -65°C to +175°C junction temperature. The component is RoHS compliant, indicated by the 'e3' suffix, and is supplied in tape and reel packaging.

Feature Summary

• Provides precise voltage regulation with a ±2% tolerance on the 130 V Zener voltage.
• Capable of handling high thermal loads with a maximum operating junction temperature of 175°C.
• Constructed with a plastic encapsulated DO-41 axial leaded package for through-hole mounting.

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in electronic systems
• General-purpose voltage regulation

Procurement Notes

Verify that the specific part number includes the 'e3' suffix to confirm RoHS compliance and lead finish specifications. Confirm the 'TR12' suffix matches the required tape and reel packaging format for automated assembly processes. Ensure the supplier provides documentation confirming the manufacturer as Microsemi Corporation or its successor entity.

Selection Notes

Select this component when a 130 V Zener voltage with strict ±2% tolerance is required. The 1 W power rating and 175°C thermal capability make it suitable for environments where higher heat dissipation is necessary compared to standard 500 mW devices. The axial leaded package is appropriate for through-hole PCB designs.

Part Context

This component belongs to the Microsemi 1EZ series of silicon Zener diodes. This series offers various voltage options from 110 V to 200 V in the same DO-41 package. The 'D2' suffix indicates the tighter ±2% tolerance variant, while 'e3' denotes environmental compliance. These diodes are engineered for reliability in demanding industrial and commercial applications.

Replacement Considerations

Compatible replacements include other 130 V Zener diodes with 1 W power rating and ±2% tolerance in the DO-41 package. Verify electrical parameters such as dynamic impedance and reverse leakage current match the original design requirements before substitution.
