1N5376AE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5376AE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in a T-18 axial-lead package. It provides an 87-volt nominal Zener voltage with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 75 ohms at a test current of 15 mA. It includes RoHS compliance indicated by the e3 suffix and tape-and-reel packaging specified by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and exhibits minimal changes of voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• Electronic systems demanding reliable operation in extreme temperatures

Single Zener Diodes Procurement Notes

Verify that the part number matches the specific suffix requirements: 'A' for ±10% tolerance, 'e3' for RoHS compliance, and 'TR' for tape-and-reel packaging. Confirm the manufacturer is Microsemi Corporation or its authorized successor entity. Ensure the component meets the required JEDEC registration standards for the 1N5376 designation before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 87-volt reference is needed with moderate tolerance. Consider the 5-watt power dissipation capability and low thermal resistance design for applications requiring high DC currents with adequate heat sinking. Verify that the T-18 axial lead package fits the mechanical constraints of the target circuit board layout.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for applications requiring reliable voltage regulation and high surge withstand capabilities.

Single Zener Diodes Replacement Considerations

Equivalent parts include the standard 1N5376 without the e3/TR suffixes if non-RoHS and loose-packaged variants are acceptable. Surface mount equivalents such as SMBJ5376A may be considered if PCB space requires a different form factor, though pinout and thermal characteristics must be verified.
