1N5381E3/TR12

Overview

The Microsemi Corporation 1N5381E3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 130V and a ±20% tolerance. It operates within a temperature range of -65°C to +150°C, features a T-18 axial lead package, and utilizes matte-tin plating for RoHS compliance.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features minimal changes in voltage versus current as specified by voltage regulation

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance levels and screening requirements. Confirm that the TR12 designation aligns with tape-and-reel packaging standards. Ensure compatibility with assembly processes regarding moisture sensitivity classification and soldering temperatures.

Selection Notes

Select this component when a 5-watt power rating and 130-volt regulation are required. Consider the thermal resistance characteristics and heat sinking needs for steady-state operation. Evaluate the plastic encapsulation benefits against environmental exposure requirements.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded Zener diodes. The series provides a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by specific suffix letters on the part number.

Replacement Considerations

Equivalent parts include 1N5381A, 1N5381C, and 1N5381D. Verify mechanical dimensions and electrical tolerances before substitution.
