SMBJ5344CE3/TR13

Single Zener Diodes Overview

The SMBJ5344CE3/TR13 is a surface mount silicon 5.0 watt Zener diode manufactured by Microchip Technology. It provides an 8.2 V nominal breakdown voltage with a +/- 2% tolerance, indicated by the 'C' suffix. The device utilizes a DO-215AA gull-wing package and operates within a junction temperature range of -65°C to +150°C. It serves as a surface mount equivalent to the JEDEC registered 1N5344B series.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with tight +/- 2% tolerance for sensitive circuitry.
• Features a gull-wing lead frame design allowing for visible solder connections in high-density mounting applications.
• Capable of withstanding high surge stresses and non-sensitive to electrostatic discharge events.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-density and low-profile surface mount mounting
• Protection against high surge stresses

Single Zener Diodes Procurement Notes

Verify the specific electrical characteristics against the official datasheet before integration. Confirm that the RoHS compliant matte-tin finish meets environmental requirements. Ensure the DO-215AA footprint matches the PCB layout. Check for any product change notifications or discontinuance updates from the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 8.2 V regulation are required. The C suffix indicates a tighter 2% tolerance compared to standard A or B variants. Consider the thermal resistance values and derating curves if operating at elevated ambient temperatures or without adequate heat sinking on FR4 boards.

Single Zener Diodes Part Context
