B320-13-F

Overview

The B320-13-F is a silicon Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration housed in an SMC (DO-214AB) surface-mount package with two pins. The device supports a maximum average forward rectified current of 3 A and a repetitive peak reverse voltage of 20 V. Key electrical parameters include a maximum forward voltage of 0.5 V at rated current, a peak non-repetitive forward surge current of 80 A, and a maximum reverse leakage current of 500 uA. It operates within a junction temperature range of -55°C to +125°C.

Feature Summary

• Guard ring die construction provides protection against transient voltage events.
• Low power loss design ensures high efficiency during operation.
• Surge overload rating accommodates high peak currents for robust performance.
• Totally lead-free and fully RoHS compliant for environmental safety.

Applications

• Free wheeling diode circuits
• Polarity protection applications
• Low voltage high frequency inverters

Procurement Notes

Verify the specific suffix '13-F' to confirm lead-free and halogen-free status. Ensure the package code matches SMC (DO-214AB). Check for AEC-Q101 qualification if automotive reliability is required, as standard versions may differ from qualified variants. Confirm moisture sensitivity level requirements for assembly processes.

Selection Notes

Select this component for low-voltage DC-DC converters requiring high efficiency. The 20 V rating suits 5 V or 12 V output stages. Compare forward voltage drop against alternatives to minimize conduction losses. Verify thermal management capabilities given the 3 A continuous current rating in the SMC package.

Part Context

This part belongs to the B3xx series of surface mount Schottky rectifiers from Diodes Incorporated. It shares the same physical footprint and general characteristics with other voltage variants in the family, such as the B340 and B360 models, differing primarily in reverse voltage blocking capability.

Replacement Considerations

Direct substitutes include B320A-13-F and B320AE-13-F, which offer identical 20 V/3 A ratings in compatible SMA packages. Verify pinout compatibility and thermal resistance differences when swapping between SMC and SMA form factors.
