SMBJ5376B/TR13

Single Zener Diodes Overview

The SMBJ5376B/TR13 is a surface mount silicon 5.0 watt Zener diode manufactured by Microchip Technology, equivalent to the JEDEC registered 1N5376B series. It features a gull-wing lead frame in the DO-215AA package and offers an 87 V nominal breakdown voltage with a ±5% tolerance. The device operates within a junction temperature range of -65°C to +150°C and provides high surge current withstand capability.

Single Zener Diodes Feature Summary

• Surface mount design suitable for high-density and low-profile mounting applications
• Equivalent electrical characteristics to the JEDEC registered 1N5376B series
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Protection against high surge stresses in electronic circuits
• General purpose Zener regulation in surface mount assemblies

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the datasheet references Microsemi while the model indicates Microchip Technology due to corporate acquisition. Confirm RoHS compliance status and terminal plating type (tin-lead or matte-tin) based on the exact ordering suffix requirements. Ensure the TR suffix matches standard EIA-481-1-A tape and reel specifications for automated assembly.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 87-volt breakdown are required in a gull-wing DO-215AA package. Consider the ±5% voltage tolerance and thermal resistance values for heat sinking calculations. Verify compatibility with FR4 printed circuit boards using the recommended footprint layout provided in the mechanical documentation.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B through SMBG5388B series of surface mount Zener diodes. The series covers a voltage selection from 3.3 to 200 volts with various tolerance options identified by suffix letters. These devices serve as direct replacements for axial-leaded 1N5333 through 1N5388 components in modern surface mount designs.

Single Zener Diodes FAQ

What is the maximum non-repetitive peak surge current for this device?

The maximum surge current (IZSM) is specified as 54.5 Amps for a non-recurrent half-sine wave of 8.3 ms duration.

How is polarity indicated on the SMBJ5376B/TR13?

Polarity is indicated by a band on the cathode end. The diode must be operated with the banded end positive with respect to the opposite end.
