B340LB-13-F Description

Short technical summary and product information.

The B340LB-13-F is a 3.0A low VF Schottky barrier rectifier from Diodes Incorporated, designed for high-efficiency rectification in surface-mount applications. It offers a very low forward voltage drop of 0.31V typical at 1A and 0.45V maximum at 3A, minimizing power loss and improving system efficiency.

 

This rectifier is rated for a peak repetitive reverse voltage of 40V and can handle a non-repetitive peak forward surge current of 70A, making it suitable for applications with transient overloads. The device is housed in an SMB (DO-214AA) package with a molded plastic case rated UL 94V-0 and weighs approximately 0.093 grams.

 

The B340LB-13-F is lead-free with matte tin terminals, RoHS compliant, and halogen and antimony free (green device). It is moisture sensitivity level 1 per J-STD-020 and is supplied in tape and reel packaging with 3000 units per reel.
