1EZ130D2/TR12

Overview

The 1EZ130D2/TR12 is a silicon Zener diode manufactured by Microsemi Corporation. It provides a nominal Zener voltage of 130 V with a tight tolerance of ±2%. The device has a maximum power dissipation rating of 1 W and is housed in a DO-41 axial leaded plastic package. It is supplied in a tape and reel format, indicated by the TR12 suffix.

Feature Summary

• Provides precise voltage regulation with a ±2% tolerance for sensitive circuit applications
• Capable of handling up to 1 W of power dissipation in a standard axial package
• Designed for through-hole mounting using the DO-41 form factor

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Voltage regulator biasing networks

Procurement Notes

Verify the specific manufacturer source, as Microsemi assets are managed by Microchip. Confirm RoHS compliance status, as the 'e3' suffix typically denotes lead-free composition while its absence may indicate leaded variants. Ensure the TR12 packaging designation matches automated assembly requirements.

Selection Notes

Select this component when a stable 130 V reference is required with tighter accuracy than standard 5% or 10% parts. The 1 W rating supports moderate current loads. Verify that the DO-41 package dimensions fit the target PCB layout and that the ±2% tolerance meets the design specifications.

Part Context

This part belongs to the 1EZ series of 1 Watt Zener diodes from Microsemi. The series offers various voltage options ranging from 110 V to 200 V. Suffixes define tolerance levels, with 'D2' indicating the ±2% grade. These components are designed for general-purpose regulation in industrial and commercial electronics.

Replacement Considerations

Compatible substitutes include other 130 V Zener diodes in the DO-41 package with ±2% tolerance and 1 W power rating. Cross-reference with Microchip's current portfolio for equivalent military or commercial grades.
