B340LA-13-F

Overview

The B340LA-13-F is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single configuration within an SMA (DO-214AC) package. The device supports a peak repetitive reverse voltage of 40 V and an average rectified output current of 3.0 A at +90°C case temperature. Non-repetitive peak forward surge current reaches 70 A. Forward voltage drop ranges from 0.310 V to 0.450 V depending on current conditions. Leakage current is specified up to 2.0 mA at maximum reverse voltage. Operating and storage temperatures span -55°C to +150°C.

Feature Summary

• Guard ring die construction provides transient protection capabilities
• Very low forward voltage drop contributes to high efficiency and reduced power loss
• Lead-free finish with matte tin plating ensures solderability per MIL-STD-208 standards
• Halogen and antimony free compliant with green device definitions

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required SMA tape and reel packaging quantity. Confirm compliance requirements including RoHS directives and halogen-free status align with project specifications. Ensure thermal management design accounts for the junction-to-terminal thermal resistance characteristics during operation.

Selection Notes

Select this component when a low forward voltage drop is critical for system efficiency in rectification tasks. The SMA package suits automated assembly processes requiring standard surface mount footprints. Consider the 70 A surge rating for circuits experiencing temporary overload conditions. Verify that the 40 V reverse voltage rating exceeds the maximum expected circuit voltage peaks.

Part Context

This part belongs to the B340LA/B series of 3.0A low VF Schottky barrier rectifiers. It shares electrical characteristics with the B340LB variant but utilizes a different physical package size. The series is designed for general-purpose rectification where low power loss and high switching speed are prioritized over high voltage blocking capabilities.

Replacement Considerations

B340LB-13-F offers identical electrical performance in an SMB package.
