1EZ130D5E3/TR12

Overview

The 1EZ130D5E3/TR12 is a silicon Zener diode manufactured by Microsemi Corporation. It provides a nominal Zener voltage of 130 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and features a unidirectional configuration. It utilizes a DO-41 (DO-204AL) axial-leaded plastic package suitable for through-hole mounting. The component complies with RoHS standards, indicated by the e3 suffix, and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation at 130 V with ±5% tolerance
• Designed for high DC current operation with adequate heat sinking
• RoHS compliant construction using lead-free terminals

Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage sources

Procurement Notes

Verify the specific manufacturer source, as Microsemi's semiconductor assets were acquired by Microchip Technology. Confirm that the e3 suffix correctly denotes RoHS compliance and lead-free termination for this specific lot. Ensure the TR12 designation matches the required tape and reel quantity for automated assembly processes.

Selection Notes

Select this component when a 130 V reference is required in a standard axial package. The 1 W power rating allows for moderate current handling compared to lower-power variants. Verify that the ±5% tolerance meets the circuit requirements, as tighter tolerances are available via different suffix codes within the same series.

Part Context

This part belongs to the 1EZ series of 1 Watt Zener Diodes from Microsemi. The series offers voltage selections ranging from 110 V to 200 V in the DO-41 plastic package. Other tolerance options are available by modifying the suffix identifier, allowing designers to choose between standard and tighter voltage accuracy specifications.

Replacement Considerations

Compatible substitutes include other 130 V, 1 W Zener diodes in the DO-41 package. Cross-reference with Microchip's current portfolio if sourcing directly from the original manufacturer. Ensure any replacement maintains the 1 W power dissipation rating and compatible thermal characteristics.
