SMBJ5371CE3/TR13

Single Zener Diodes Overview

The Microchip Technology SMBJ5371CE3/TR13 is a surface mount silicon 5.0 watt Zener diode in the DO-214AA (SMB) package. It provides a nominal breakdown voltage of 60 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a junction temperature range of -65°C to +150°C and features RoHS compliant matte-tin plating. It serves as a surface mount equivalent to the JEDEC registered 1N5371B series, offering high-density mounting capabilities.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with ±2% tolerance for stable performance across operating ranges.
• Features a gull-wing lead frame design allowing for visible solder connections in the DO-215AA package.
• Withstands high surge stresses and exhibits minimal changes of voltage versus current.
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B, requiring no dry pack.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• High-density and low-profile circuit board mounting.
• Protection against high surge stresses in electronic circuits.

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the TR13 suffix to confirm tape and reel packaging compliance with EIA-481-1-A standards. Ensure the C suffix is present to guarantee the required ±2% voltage tolerance. Confirm RoHS compliance via the e3 designation if lead-free requirements are mandatory for the assembly process.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and a 60 V breakdown voltage are required with strict ±2% tolerance. It is suitable for applications needing surface mount equivalents to axial-leaded 1N5371B devices. Consider the thermal resistance values and derating curves for proper heat sinking on FR4 PCBs to maintain reliability at elevated temperatures.

Single Zener Diodes Part Context

This device belongs to the SMBG5333B through SMBG5388B series of surface mount 5.0 watt Zener diodes manufactured by Microsemi/Microchip. The series covers a voltage selection from 3.3 to 200 volts. The SMBJ variant specifically utilizes the DO-214AA J-bend package, while the SMBG uses the DO-215AA gull-wing package, both sharing identical electrical characteristics.

Single Zener Diodes Replacement Considerations

The SMBJ5371CE3/TR13 is electrically equivalent to the 1N5371B series. For direct replacement, verify that the substitute part matches the 60 V nominal voltage, 5 W power dissipation, and ±2% tolerance specifications.
