1EZ130DE3/TR12

Overview

The 1EZ130DE3/TR12 is a silicon Zener diode manufactured by Microsemi Corporation. It provides a nominal Zener voltage of 130 V with a tolerance of ±10%. The device has a maximum power dissipation rating of 1 W and is housed in a DO-204AL (DO-41) axial leaded plastic package. It is RoHS compliant and supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation at 130 V with standard manufacturing tolerances.
• Utilizes a robust plastic encapsulated DO-41 axial leaded package for through-hole mounting.
• Constructed from silicon material for reliable unidirectional operation.

Applications

• General purpose voltage regulation circuits
• Power supply reference voltage generation
• Over-voltage protection stages

Procurement Notes

Verify the specific suffix 'E3' confirms RoHS compliance status against current manufacturer documentation, as regulatory statuses can change. Confirm the 'TR12' designation matches the required tape and reel quantity specifications for your automated assembly equipment. Ensure the DO-41 package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 130 V reference point is required within a 1 W power budget. The DO-41 package is suitable for applications requiring through-hole technology. Consider the ±10% tolerance if tighter voltage precision is not critical for the circuit design. Verify thermal management capabilities are sufficient for continuous operation at full power ratings.

Part Context

This part belongs to the Microsemi 1EZ series of 1-watt Zener diodes. The series offers various voltage options within the same DO-41 plastic package form factor. The 'E3' suffix typically indicates environmental compliance, while 'TR12' denotes the specific reel packaging format used for high-volume surface or through-hole mounting processes.

Replacement Considerations

Compatible replacements include other 130 V, 1 W Zener diodes in the DO-41 package such as the 1N5380B or equivalent generic industrial grade parts. Ensure any substitute maintains the same ±10% tolerance and thermal characteristics. Verify that the replacement part's reverse leakage current and impedance values meet the original circuit requirements.
