B320AF-13 Description

Short technical summary and product information.

B320AF-13 is a 20V, 3A Schottky barrier rectifier diode from Diodes Incorporated, designed for general rectification applications. It offers a low forward voltage drop of 0.50V maximum at 3A, which improves efficiency and reduces operating temperature. The device also features low reverse leakage current of 0.2mA at 25°C and high surge current capability of 80A.

The diode is housed in a compact SMAF (DO-221AC) surface mount package with a weight of only 0.036 grams. It is RoHS compliant, halogen and antimony free, and has a UL 94V-0 flammability rating. The operating temperature range is -55°C to 150°C, making it suitable for a variety of environments.

Typical applications include boost diodes, blocking diodes, and recirculating diodes in power supply and conversion circuits. The low VF and excellent reverse leakage stability at high temperatures enhance reliability in high-temperature operation.
