1N5381CE3/TR8

Overview

The Microsemi Corporation 1N5381CE3/TR8 is a silicon Zener diode with a nominal voltage of 130V and a tolerance of ±2%. It features a 5W power dissipation rating, unidirectional polarity, and a T-18 plastic axial lead package. The device is RoHS compliant and supplied in tape and reel packaging.

Feature Summary

• Provides precise voltage regulation within tight tolerances
• Capable of handling high surge stresses
• Offers flexible axial-lead mounting terminals

Applications

• Voltage regulation over broad operating current ranges
• High power dissipation applications requiring adequate heat sinking
• Circuits requiring minimal voltage change versus current

Procurement Notes

Verify the specific suffix configuration to confirm RoHS compliance and tape-and-reel packaging format. Ensure the ordering part number matches the required tolerance level and screening standards for your application requirements.

Selection Notes

Select this component when a stable 130V reference with ±2% accuracy is needed. Consider the 5W power rating and thermal resistance characteristics for proper heat sinking design to maintain performance within specified temperature limits.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide voltage selection from 3.3V to 200V with various tolerance options defined by suffix letters.

Replacement Considerations

Equivalent parts include other 1N5381 variants with matching voltage and tolerance specifications. Verify that substitute components meet the same power dissipation and package requirements.
