1EZ130D5/TR12

Overview

The Microsemi Corporation 1EZ130D5/TR12 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 130 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within an axial-lead DO-41 plastic package. Key electrical characteristics include a reverse current of 500 nA at 98.8 V and a unidirectional configuration.

Feature Summary

• Provides stable voltage regulation with a nominal reference voltage of 130 V
• Engineered for high reliability in plastic encapsulated axial packages
• Offers tight manufacturing tolerances for precise circuit performance

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify the specific suffix 'TR12' to confirm tape-and-reel packaging requirements. Ensure compatibility with the DO-41 leaded form factor. Confirm RoHS compliance status if required by assembly specifications. Cross-reference datasheet revisions to validate thermal and electrical parameters against current design constraints.

Selection Notes

Select this component when a 130 V regulation point is required in a standard axial package. The 1 W power rating suits moderate current applications. Consider the ±5% tolerance for budgeting voltage accuracy. Verify that the DO-41 footprint aligns with the target PCB layout and mounting constraints.

Part Context

This part belongs to the Microsemi 1EZ series of 1 Watt Zener diodes. The series offers various voltage options from 110 V to 200 V in the DO-41 package. The 'D5' suffix indicates the 5% tolerance grade, while 'TR12' specifies the reel quantity and packaging format for automated assembly processes.

Replacement Considerations

Compatible substitutes include other 130 V, 1 W Zener diodes in the DO-41 package with ±5% tolerance. Verify equivalent power ratings and leakage currents before substitution.
