Additional Details

The UF802F is typically available in a TO-220F package. The key electrical specifications include a repetitive peak reverse voltage (VRRM) of 200V, a maximum average forward rectified current (IF(AV)) of 8.0A, and a typical forward voltage drop (VF) of around 0.95V to 1.2V (depending on the specific operating conditions). The ultrafast recovery time (trr) is a crucial characteristic, usually in the range of tens of nanoseconds. This rapid switching speed minimizes reverse recovery losses, which are a significant source of inefficiency in high-frequency circuits. The high surge current capability provides protection against transient voltage spikes and overcurrent conditions, enhancing the overall reliability of the application. The device's low forward voltage drop reduces power dissipation, further improving the overall energy efficiency. The insulated TO-220F package improves thermal performance by allowing the device to be mounted directly to a heatsink with only a single screw.

The UF802F is commonly used in various power electronics applications where both speed and efficiency are essential. The fast recovery characteristic helps reduce 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.
