SMBJ5339C/TR13

Single Zener Diodes Overview

The Microsemi SMBJ5339C/TR13 is a surface mount silicon Zener diode with a nominal breakdown voltage of 5.6 V and a tight tolerance of ±2%. It operates in the DO-214AA (SMB) package, providing a rated power dissipation of 5.0 W at a lead temperature below 25 °C. The device features a maximum reverse leakage current of 10 µA at 2.0 V and a dynamic impedance of 1.0 Ω at a test current of 220 mA. It withstands a non-repetitive surge current of 400 A and functions within a junction temperature range of -65 °C to +150 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±2% breakdown voltage tolerance for sensitive circuitry.
• Engineered with a gull-wing lead frame design to facilitate visible solder connections during assembly.
• Capable of withstanding high surge stresses and maintaining stable performance across broad operating currents.
• Classified as Level 1 moisture sensitivity, eliminating the requirement for dry packaging.

Single Zener Diodes Applications

• Voltage regulation in high-density electronic assemblies
• Protection against electrical fast transients (EFT)
• Surge suppression in low-profile mounting environments

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the 'TR' 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 status by checking for the 'e3' designation if matte-tin plating is required. Cross-reference the JEDEC type number to ensure identical electrical characteristics are maintained.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference requires tighter than standard manufacturing tolerances. The DO-214AA package is suitable for applications demanding low-profile surface mount configurations. Verify thermal management requirements, as the maximum regulator current depends on the available heat sinking and ambient temperature conditions.
