B240-13-G

Overview

The B240-13-G is a surface-mount Schottky rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SMB (DO-214AA) package. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 40 V and an average forward rectified current (If) of 2 A. The device exhibits a maximum forward voltage (Vf) of 500 mV at rated current and supports a peak non-repetitive forward surge current (Ifsm) of 50 A. Operating temperature ranges from -65°C to +150°C junction temperature.

Feature Summary

• Guard ring die construction designed for transient protection
• Low power loss characteristics contributing to high efficiency
• Optimized structure for automated assembly processes

Applications

• General purpose rectification in low voltage DC circuits
• Power supply input rectification stages
• Free-wheeling diode applications in switching regulators

Procurement Notes

Verify component status carefully as this specific suffix variant may be obsolete or discontinued. Confirm availability through authorized distributors or check for active replacement part numbers such as the -13-F series if production continuity is required. Ensure datasheet revisions match the manufacturing date code for accurate parameter validation.

Selection Notes

Select this component for applications requiring a 40 V rating with 2 A continuous current capability in a compact SMD footprint. Consider the -13-F variant if the -G suffix is unavailable, as it shares identical electrical specifications and physical dimensions. Evaluate thermal management requirements based on the 150°C maximum junction temperature limit during circuit design.

Part Context

This component belongs to the B240 series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings within the same package family. The B240 specifically denotes the 40 V blocking voltage class. These devices are engineered for general-purpose rectification tasks where low forward voltage drop and fast switching speeds are prioritized over high reverse breakdown voltages.

Replacement Considerations

The B240-13-F is a confirmed substitute with identical electrical and mechanical specifications. Other compatible replacements include the B240Q-13-F which adds automotive qualification. Verify pinout compatibility and package tolerance before substituting.
