Description

Marked "FFPF20UA60DN" on the package with ON Semiconductor's logo, this is ON Semiconductor's (formerly Fairchild) FFPF20UA60DN, an Ultrafast Dual Diode in a common cathode configuration. It is featuring low forward voltage drop and ultrafast recovery duration ( t rr < 45 ns ), engineered to minimize switching losses and electromagnetic interference (EMI) in high-frequency power conversion systems.

Housed in a fully isolated TO-220F package, it allows direct heat-sink mounting without requiring external isolation pads, making thermal assembly fast and efficient.
