Overview
The B340AF-13-2477 is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications. It features a single diode configuration within the SMAF (DO-219AA) package. The device supports a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 3 A. Key electrical characteristics include a low forward voltage drop of 500 mV at rated current and a non-repetitive peak forward surge current capability of 80 A. The component operates reliably across a junction temperature range from -55 °C to +150 °C.
Feature Summary
- Utilizes Schottky barrier technology to achieve low forward voltage drop and high efficiency.
- Features a compact SMAF surface-mount package suitable for automated assembly processes.
- Incorporates a guard ring structure for enhanced transient protection capabilities.
Applications
- DC-DC converters
- Power supply circuits
- Free-wheeling diodes in inductive load switching
Procurement Notes
Verify the specific suffix '2477' against the official manufacturer datasheet to confirm if it denotes a unique packaging variant or tape-and-reel specification distinct from the standard B340AF-13 part number. Ensure compliance with RoHS directives and check for REACH SVHC status prior to integration into final assemblies.
Selection Notes
Select this component when a low-profile SMAF footprint is required for 3 A rectification tasks. The 40 V rating suits low-voltage DC systems. Compare the 500 mV forward voltage against alternatives to ensure thermal management requirements are met within the specified operating temperature range.
Part Context
This part belongs to the B3xxA series of Schottky rectifiers from Diodes Incorporated. It shares core electrical specifications with variants like the B340A-13-F but differs in physical packaging, utilizing the smaller SMAF case instead of the standard SMA (DO-214AC). This series is engineered for general-purpose rectification in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include other 40 V, 3 A Schottky diodes in the SMAF package. Verify pinout compatibility and thermal resistance values before swapping. Generic equivalents must match the 500 mV forward voltage and 80 A surge current ratings to maintain circuit performance integrity.
