1N5380E3/TR13

Overview

The Microsemi 1N5380E3/TR13 is a silicon 5-watt Zener diode with a nominal voltage of 120V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 170 ohms at a test current of 12mA. The device has a maximum reverse current of 0.5µA and supports a maximum regulator current of 39.5mA. Packaged in an axial-lead case with RoHS-compliant tin plating, it includes a tape-and-reel option for automated assembly.

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 suitable for various board layouts
• Non-sensitive to electrostatic discharge per specified military testing methods

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in measurement equipment

Procurement Notes

Verify the specific suffix configuration against the datasheet to ensure correct tolerance and packaging. Confirm that the e3 suffix indicates RoHS compliance and the TR13 suffix denotes tape-and-reel packaging. Cross-reference the part number with official Microsemi documentation to validate authenticity and manufacturing origin before procurement.

Selection Notes

Select this component when a 120V Zener reference with 5W power dissipation is required. Ensure adequate heat sinking is provided to maintain operation within thermal limits. Verify that the ±5% tolerance meets circuit requirements. Consider the axial lead format for through-hole mounting or the reel option for surface mount compatibility if applicable.

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. The 1N5380 variant specifically targets the 120V regulation segment. The e3 suffix denotes environmental compliance, while TR13 indicates bulk tape-and-reel packaging for high-volume production.

Replacement Considerations

Direct substitutes include other 1N5380 variants with different suffixes for tolerance or packaging, such as 1N5380B (standard) or 1N5380E3 (RoHS compliant). Surface mount equivalents like SMBJ5380B may be considered if footprint changes are acceptable. Verify thermal resistance and package dimensions match the existing design constraints.
