FFH30S60STU

FFH30S60STU Description

The FFH30S60STU from onsemi is a high-performance 600V, 30A general-purpose rectifier diode housed in a TO-247-2 package. Designed for demanding applications, it features a fast recovery time of 40 ns, making it suitable for high-frequency switching circuits. With a low forward voltage drop of 2.6V at 30A, it ensures efficient power conversion while minimizing heat dissipation. The diode complies with ROHS3 and REACH environmental standards, and its through-hole mounting provides robust mechanical stability. Although marked as obsolete, its high reverse voltage capability (600V) and low reverse leakage current (100µA @ 600V) make it a reliable choice for legacy designs.
