1N5380AE3/TR8

Overview

The Microsemi Corporation 1N5380AE3/TR8 is a silicon Zener diode with a nominal voltage of 120 V and a tolerance of ±10%. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes a T-18 plastic axial-lead package and includes an e3 suffix indicating RoHS compliance. The TR8 suffix designates tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses without damage
• Exhibits minimal changes in voltage versus current as specified by voltage regulation

Applications

• Voltage regulation over broad operating current and temperature ranges
• Circuit protection against high surge stresses
• General purpose voltage reference applications

Procurement Notes

Verify the specific suffixes on the component marking to confirm RoHS compliance (e3) and tape and reel packaging (TR). Ensure the ordering part number matches the required ±10% tolerance designation (A suffix) and the 120 V nominal voltage rating. Confirm that the manufacturer documentation aligns with the requested specifications before finalizing procurement.

Selection Notes

Select this component when a 5-watt power rating and a 120 V nominal Zener voltage are required. The ±10% tolerance suits general-purpose regulation where tighter precision is unnecessary. Consider the T-18 package dimensions and thermal resistance characteristics for adequate heat sinking during operation.

Part Context

This device belongs to the JEDEC registered 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes. The series provides a wide selection of voltages from 3.3 V to 200 V. The 1N5380 variant specifically targets the 120 V segment of this product line, offering standard commercial screening levels.

Replacement Considerations

Equivalent parts include other manufacturers' 1N5380 variants or the 1N5380B for tighter tolerances. Surface mount equivalents such as SMBJ5380 or SMBG5380 may be considered if board space requires a different form factor.
