1EZ130D2/TR8

Overview

The 1EZ130D2/TR8 is a silicon unidirectional Zener diode manufactured by Microsemi Corporation. It provides 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. This component is supplied in tape and reel packaging, designated by the /TR8 suffix, facilitating automated surface mounting processes.

Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance on the 130 V breakdown voltage.
• Engineered for high-power operation with a 1 W maximum power dissipation rating.
• Constructed in a standard DO-204AL plastic axial package for through-hole integration.

Applications

• Precision voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications within power supply output stages.

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel quantity matches the required production volume. Confirm that the ±2% tolerance designation aligns with the circuit's precision requirements. Ensure the DO-204AL package dimensions fit the target PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 130 V regulation point is needed with higher accuracy than standard 5% or 10% variants. The 1 W power rating allows for robust performance in moderate current scenarios. The axial leaded format is suitable for applications where surface mount space is limited but through-hole reliability is preferred. Compare against other series members for alternative voltage or tolerance options.

Part Context

This part belongs to the Microsemi 1EZ series of plastic encapsulated Zener diodes. The series offers various voltage selections from 3.6 V to 200 V. The 'D2' suffix specifically denotes the tighter ±2% tolerance band, distinguishing it from standard tolerance versions like D5 or D10. These devices are designed for general-purpose voltage regulation in industrial and commercial electronics.

Replacement Considerations

Equivalent parts include 1EZ130D5/TR8 for looser tolerance or 1EZ130D1/TR8 for even tighter specifications. Cross-reference with JAN1N4743A for military-grade equivalents if screening levels are required. Verify pinout compatibility and thermal characteristics before substitution.
