ONSEMI FS8J Surface Mount Rectifier

The FS8M series includes surface mount rectifiers capable of handling 8 A DC forward current with a peak surge current of 230 A, ideal for space-constrained applications. They feature low reverse leakage current of 0.37 μA, very high surge capabilities, and are mounted in an ultra-compact TO-277 package with a typical height of just 1.1 mm. These devices are glass passivated, RoHS compliant, and suitable for general-purpose rectification, reverse polarity protection, and semiconductor applications in rugged operating environments.
