SMBJ5920C/TR13

Single Zener Diodes Overview

The SMBJ5920C/TR13 is a surface-mount 2.0 W Zener diode from the SMBJ59 family, manufactured by Microchip Technology. It utilizes the DO-214AA (SMB) package with a J-bend design for high-density mounting. The device provides a nominal Zener voltage of 6.2 V with a ±2% tolerance and operates within a junction temperature range of –65 °C to +150 °C. It features low thermal resistance and meets Level 1 moisture classification standards.

Single Zener Diodes Feature Summary

• High-density and low-profile mounting capability via the SMBJ J-bend design in the DO-214AA package.
• Low thermal resistance enabling operation at high maximum DC currents when adequately heat sunk.
• Level 1 moisture classification requiring no dry pack per IPC/JEDEC J-STD-020F.
• Non-sensitive to electrostatic discharge as verified by MIL-STD-750 method 1020.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Protection against high surge stresses

Single Zener Diodes Procurement Notes

Verify the specific part number suffix against official documentation to confirm plating type and packaging configuration. Confirm availability status directly with the manufacturer or authorized distributors, as product discontinuance notifications may affect supply chain continuity for this component series.

Single Zener Diodes Selection Notes

Select this component for applications requiring precise voltage regulation with tight tolerances in a compact surface-mount footprint. Ensure adequate heat sinking is provided if operating near the maximum rated power dissipation limits to maintain performance within specified thermal boundaries.

Single Zener Diodes Part Context

This component belongs to the SMBJ59 family of silicon Zener diodes, which are electrically equivalent to the JEDEC registered 1N5918–1N5924 axial-lead series but offer a higher power rating of 2.0 W compared to the 1.5 W rating of the axial equivalents.

Single Zener Diodes Replacement Considerations

The SMBJ5920C is functionally equivalent to the axial-lead 1N5920B. Verify pinout compatibility and thermal management requirements when transitioning between the SMBJ surface-mount package and traditional through-hole implementations.
