B390-13-F

Overview

The B390-13-F is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a maximum repetitive peak reverse voltage of 90 V and an average forward rectified current rating of 3 A. The device exhibits a maximum forward voltage drop of 790 mV at 3 A. Electrical characteristics include a maximum reverse leakage current of 500 µA at 90 V and a junction capacitance of 100 pF measured at 4 V and 1 MHz. The component operates within a junction temperature range of -55°C to 125°C and utilizes the SMC (DO-214AB) package.

Feature Summary

• Guard ring die construction provides enhanced transient protection capabilities.
• Low power loss design ensures high efficiency in rectification applications.
• Surge overload rating supports high current transients up to 125 A peak.
• Lead-free finish with RoHS compliance and halogen-free composition.

Applications

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

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm package type and electrical ratings. Ensure the procurement channel sources genuine components from authorized distributors. Confirm RoHS3 and REACH compliance status for regulatory adherence. Validate that the received parts match the SMC package designation and do not contain unauthorized substitutions or generic family variants.

Selection Notes

Select this component when a 90 V reverse voltage rating and 3 A continuous current capacity are required in a surface-mount configuration. The SMC package offers a compact footprint suitable for automated assembly processes. Consider the low forward voltage drop for efficiency optimization in low-voltage DC-DC conversion or power supply designs where thermal management is critical.

Part Context

This part belongs to the B370-B3100 series of surface mount Schottky barrier rectifiers produced by Diodes Incorporated. The series shares common manufacturing technologies and mechanical standards while varying in voltage ratings. The B390 variant specifically targets applications requiring higher reverse voltage blocking capability compared to lower-rated siblings like the B340 or B360.

Replacement Considerations

Compatible substitutes within the same series include B370-13-F, B380-13-F, and B3100-13-F. These alternatives share identical package dimensions and current ratings but differ in maximum reverse voltage specifications. Verify that the substitute's voltage rating meets or exceeds the circuit requirements before implementation.
