B350-13-F

Overview

The B350-13-F is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration housed in the SMB (DO-214AA) package. The device supports a maximum average forward rectified current of 3 A and a repetitive peak reverse voltage of 50 V. Key electrical parameters include a maximum DC reverse voltage of 50 V, a maximum forward voltage drop of 0.7 V at 3 A, and a maximum reverse leakage current of 0.5 mA. The component operates within a temperature range of -55°C to +150°C and withstands a non-repetitive peak forward surge current of 100 A.

Feature Summary

• Guard ring die construction provides enhanced transient protection capabilities for improved reliability under varying electrical conditions.
• Low power loss design contributes to high efficiency, making the component suitable for applications requiring minimal energy dissipation.
• Surge overload rating allows the device to handle significant temporary current spikes without failure.

Applications

• Free wheeling diode circuits in low voltage power supplies
• Polarity protection mechanisms in electronic systems
• Low voltage, high frequency inverters

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm exact packaging and tape-and-reel specifications. Ensure compliance with RoHS directives and check for AEC-Q101 qualification if automotive-grade reliability is required. Confirm the SMB package dimensions match the target PCB footprint before integration.

Selection Notes

Select this component when a 3 A continuous current rating and 50 V blocking voltage are required in a compact surface-mount form factor. The SMB package offers a balance between current handling capacity and board space efficiency compared to smaller SOD packages. Consider the 0.7 V forward voltage drop for thermal management calculations in high-efficiency designs.

Part Context

This part belongs to the B3xx series of Schottky rectifiers from Diodes Incorporated, designed for general-purpose rectification in surface-mount applications. The series utilizes silicon technology to provide fast switching characteristics and low forward voltage drops. The B350 variant specifically targets 50 V applications within this lineup.

Replacement Considerations

Cross-reference with other manufacturers offering SMB-packaged 3 A, 50 V Schottky diodes. Verify pinout compatibility and thermal resistance values. Ensure equivalent surge current ratings and reverse leakage specifications match the original design requirements.
