Additional Details

The UF803CT is typically available in a TO-220AB package. Key electrical characteristics include a repetitive peak reverse voltage (VRRM) of 300V, a maximum average forward rectified current (IF(AV)) of 4.0A per diode (8.0A total), and a low forward voltage drop (VF) of around 1.3 V. The ultrafast recovery time (trr), usually in the range of tens of nanoseconds, enables efficient operation in high-frequency circuits by minimizing reverse recovery losses. The common cathode configuration simplifies circuit layout in certain applications. The device is designed to handle significant surge currents, enhancing its reliability in demanding applications. Its low forward voltage drop contributes to reduced power losses and improved overall efficiency.

This dual ultrafast recovery rectifier is a commonly used component in various power electronics applications where both speed and efficiency are important, and a common cathode configuration is required. The fast recovery characteristic minimizes reverse recovery losses, making it suitable for high-frequency switching circuits. The robust design and high surge current capability contribute to its reliability in harsh operating environments. Its RoHS compliance ensures that it meets environmental regulations.
