SMBJ5930BE3/TR13

Single Zener Diodes Overview

The SMBJ5930BE3/TR13 is a surface mount 2.0 W Zener diode from the SMBJ59 family, housed in a DO-214AA (SMB) package with J-bend terminals. It provides a nominal Zener voltage of 6.8 V with a ±5% tolerance and operates within a junction temperature range of –65 °C to +150 °C. The device features low thermal resistance for high DC current operation and meets Level 1 moisture classification standards.

Single Zener Diodes Feature Summary

• Surface-mount design optimized for high-density and low-profile PCB mounting
• Low thermal resistance enabling higher maximum DC currents compared to axial equivalents
• Level 1 moisture classification requiring no dry pack storage
• RoHS compliant matte-tin plating available with the e3 suffix

Single Zener Diodes Applications

• Voltage regulation across broad operating current and temperature ranges
• Protection against high surge stresses
• Replacement for JEDEC registered 1N5918–1N5924 series components

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required Zener voltage and tolerance class. Confirm the presence of the TR13 suffix indicates tape-and-reel packaging. Ensure the e3 suffix is present if RoHS compliance is mandatory for the assembly process.

Single Zener Diodes Selection Notes

Select this component when a 2.0 W power rating is required in a compact surface-mount form factor. Consider the DO-214AA package dimensions for board space constraints. Verify that the 6.8 V nominal voltage aligns with the circuit's regulation requirements.

Single Zener Diodes Part Context

This device belongs to the SMBJ59 family of silicon Zener diodes manufactured by Microchip Technology. The family covers Zener voltages from 5.1 V to 9.1 V and serves as a direct electrical equivalent to the legacy 1N5918 through 1N5924 axial-lead series, offering improved power handling capabilities.

Single Zener Diodes Replacement Considerations

The SMBJ5930BE3/TR13 is electrically equivalent to the 1N5920B Zener diode. Designers replacing axial components should account for the physical differences between the DO-214AA surface-mount package and traditional through-hole leads.
