1N5381E3/TR8

Overview

The Microsemi 1N5381E3/TR8 is a silicon Zener diode with a nominal voltage of 130V and a tolerance of ±5%. It features a maximum power dissipation of 5W at 25°C, operating temperatures from -65°C to +150°C, and a thermal resistance of 25°C/W junction-to-lead. The device utilizes an axial T-18 plastic package with tin-plated leads, complies with RoHS standards, and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for versatile integration

Applications

• Voltage regulation circuits requiring 130V reference
• Power supply protection against overvoltage conditions
• General-purpose clamping applications in electronic systems

Procurement Notes

Verify the specific suffix configuration to confirm compliance requirements and packaging format. Ensure the ordering code matches the required RoHS status and reel specifications. Cross-reference the part number with official Microsemi documentation to validate electrical characteristics and mechanical dimensions before finalizing procurement decisions.

Selection Notes

Select this component when a 130V Zener voltage with ±5% tolerance is required. Consider the 5W power rating and thermal management needs for the intended application environment. Verify that the axial leaded package and tape-and-reel delivery method align with the manufacturing assembly processes.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt silicon Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options. The e3 suffix indicates RoHS compliance, while the TR8 suffix specifies tape and reel packaging.

Replacement Considerations

Equivalent parts within the 1N5333B-1N5388B series may be considered if voltage and tolerance match. Verify compatibility with MIL-PRF-19500 screening levels if military-grade reliability is required.
