B240S1F-7-2477

Overview

The B240S1F-7-2477 is a surface-mount Schottky rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SOD-123F package. Key electrical parameters include a maximum repetitive peak reverse voltage (Vrrm) of 40 V and a continuous forward current (If) of 2 A. The device exhibits a typical forward voltage (Vf) of 500 mV at rated current and a maximum reverse leakage current (Ir) of 500 uA. It supports a peak forward surge current (Ifsm) of 50 A and operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop and high switching efficiency.
• Designed with a guard ring structure for enhanced ruggedness and reliability under stress conditions.
• Constructed using silicon (Si) semiconductor material for stable performance across wide temperature ranges.

Applications

• General-purpose rectification in low-voltage DC power supplies
• Protection circuits in automotive electronic modules
• Freewheeling diodes in inductive load switching applications

Procurement Notes

Verify the exact part number suffix against official Diodes Incorporated documentation, as variations such as -7 or -13-F may indicate different packaging or reel specifications. Confirm that the specific variant matches your required tape-and-reel quantity and handling standards. Ensure compliance with RoHS directives if applicable to your manufacturing process. Cross-reference datasheets for any recent product change notifications (PCN) affecting pinout or material composition.

Selection Notes

Select this component when a compact surface-mount solution is required for 40 V, 2 A rectification tasks. The SOD-123F package offers space savings compared to larger axial leads while maintaining thermal robustness. Consider the low forward voltage characteristic for improving overall system efficiency in battery-powered or energy-sensitive designs. Validate thermal management requirements based on the specified operating temperature range and ambient conditions.

Part Context
