The Diodes Incorporated B340LA-13-F is a 40V, 3A low-forward-voltage Schottky barrier rectifier featuring guard-ring die construction for transient protection. It is designed for low-voltage high-frequency inverters, freewheeling, polarity protection, and efficient power rectification applications.
The device is rated for 40V peak repetitive reverse voltage and 3A average rectified output current at the specified terminal temperature of +90°C. Non-repetitive peak forward surge current is rated up to 70A.
Its low forward-voltage characteristics help minimize conduction losses. Maximum VF is 0.35V at 1A and 0.45V at 3A, with approximately 0.31V typical at 1A under the datasheet test conditions.
Maximum reverse leakage is 150µA at 15V, 1mA at 20V, and 2mA at 40V. Typical total capacitance is 180pF at 1MHz and 4V reverse bias, while typical junction-to-terminal thermal resistance is 35°C/W. Operating and storage temperature range is -55°C to +150°C.
The exact B340LA-13-F uses an SMA surface-mount package and is supplied in 5,000-piece tape-and-reel packaging. It is MSL Level 1, lead-free, RoHS compliant, and halogen/antimony free. Diodes’ current product page identifies B340LA as AEC Qualified.
The 2024 EOL notice applies to B340LA-LS, not the standard B340LA-13-F. An earlier EOL notice for the special B340LA-13-F-2477 variant specifically named B340LA-13-F as its recommended replacement.
