B320B-13-F-2477

Overview

The B320B-13-F-2477 is a single Schottky rectifier diode manufactured by Diodes Incorporated. It features a maximum repetitive reverse voltage (Vrrm) of 20 V and a continuous forward current (If) of 3 A. The device utilizes an SMB surface-mount package with two pins. Key electrical parameters include a maximum forward voltage (VF) of 0.5 V, a peak non-repetitive forward surge current (Ifsm) of 100 A, and a reverse leakage current (Ir) of 100 µA at 20 V. The junction capacitance is specified as 200 pF at 4 V and 1 MHz. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Guard ring die construction provides transient protection capabilities
• Low power loss design ensures high efficiency in rectification applications
• Ideally suited for automatic assembly processes due to surface mount configuration

Applications

• Power supply circuits requiring efficient rectification
• Free-wheeling diode applications in inductive load switching
• General purpose rectification in low voltage DC systems

Procurement Notes

Verify the specific suffix -2477 against official Diodes Incorporated documentation to confirm packaging or tape-and-reel specifications. Ensure compatibility with RoHS standards if required by the end application. Cross-reference the exact part number with authorized distributors to avoid counterfeit components. Confirm lead times and minimum order quantities directly with suppliers prior to procurement.

Selection Notes

Select this component when a 20 V rating and 3 A current capacity are required in an SMB package. Consider the low forward voltage drop for efficiency-critical designs. Evaluate the 100 µA leakage current against thermal management requirements. Compare surge current ratings with circuit inrush conditions to ensure adequate safety margins during startup phases.

Part Context

This component belongs to the B320 series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings within the same package family. The B320B variant specifically denotes the 20 V blocking capability. These devices are designed for general-purpose rectification where speed and efficiency are prioritized over high voltage handling.

Replacement Considerations

Compatible substitutes include B320A-13-F and B320-13-F from the same manufacturer, provided package and electrical ratings match. Verify pinout compatibility and thermal characteristics before substitution. Ensure any alternative meets the same automotive or industrial qualification standards if applicable.
