1N5380BE3/TR8

Overview

The Microsemi Corporation 1N5380BE3/TR8 is a silicon unidirectional voltage regulator diode belonging to the JEDEC registered 1N5333B through 1N5388B series. It features a nominal Zener voltage of 120 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device is rated for a maximum power dissipation of 5.0 watts at 25°C and operates within a temperature range of -65°C to +150°C. Packaged in a T-18 axial lead format, it utilizes a void-free transfer molded thermosetting epoxy body. The 'e3' suffix confirms RoHS compliance, while 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 suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

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

Procurement Notes

Verify that the ordering suffixes match the required specifications: 'B' indicates ±5% tolerance, 'e3' denotes RoHS compliance, and 'TR8' specifies tape and reel packaging. Confirm the manufacturer is Microsemi Corporation or its authorized successor entity. Ensure the component meets the specified thermal resistance and power dissipation requirements for the intended application environment.

Selection Notes

Select this component when a 120 V Zener voltage with ±5% tolerance is required for 5-watt power dissipation applications. Consider the T-18 package for through-hole mounting and verify compatibility with the operating temperature range of -65°C to +150°C. Evaluate thermal management needs, as the device requires adequate heat sinking to maintain performance at maximum DC currents.

Part Context

This part belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by specific suffix letters. These devices are designed for applications requiring robust voltage regulation and high surge current handling capabilities.

Replacement Considerations

Equivalent parts include other 120 V, 5 W Zener diodes in the T-18 package with ±5% tolerance. Verify electrical characteristics such as dynamic impedance and reverse leakage current against the original datasheet specifications before substitution.
