FERD15S50DJF-TR – 15 A, 50 V FERD rectifier in PowerFlat 5x6
The STMicroelectronics FERD15S50DJF-TR is a Field Effect Rectifier Diode (FERD) rated for 50 V reverse voltage and 15 A average rectified current, housed in an 8-PowerVDFN PowerFlat 5x6 package for surface-mount assembly. Its forward voltage drop is 480 mV typical at 10 A forward current, which directly sets the conduction loss floor in the application – lower Vf means less heat to manage at a given load.
Switching speed and recovery behaviour
The recovery speed is classified as Fast Recovery ≤ 500 ns at > 200 mA forward current – this is not an ultrafast diode, so it is suited for line-frequency rectification, OR-ing, and freewheeling in moderate-speed converters, but not for 100 kHz+ hard-switching topologies where a sub-100 ns trr part would be needed.
No official second-source or pin-compatible cross-reference is listed, so the BOM relies on this single ST order code.
