1N5380AE3/TR12

Overview

The Microsemi Corporation 1N5380AE3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 120 V and ±10% tolerance. It operates within a temperature range of -65°C to +150°C, features an axial-lead T-18 package, and includes a TR suffix for tape-and-reel packaging.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and offers minimal voltage change versus current
• Features flexible axial-lead mounting terminals suitable for various applications

Applications

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

Procurement Notes

Verify the component's authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status and ensure the specific ordering suffix matches project requirements. Validate that the supplier provides traceable documentation for this discontinued or legacy part number.

Selection Notes

Select this component when a 120 V Zener voltage with 5 W power dissipation is required. The ±10% tolerance suits general-purpose regulation. Ensure adequate heat sinking is provided to maintain performance at maximum DC currents.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zeners. The 'e3' suffix indicates lead-free construction, while 'TR12' specifies tape-and-reel packaging. These plastic encapsulated diodes are designed for robust operation in demanding environments.

Replacement Considerations

Equivalent parts include the standard 1N5380A without the e3 or TR12 suffixes. Surface mount equivalents such as SMBJ5380A may be considered if board space allows.
