Additional Details:

The 50WQ10FNPBF features a maximum repetitive peak reverse voltage (VRRM) of 100V and a forward current (IF) of 5.0A. The forward voltage drop (VF) is typically around 0.6V at the rated current. The operating junction temperature range is typically -55°C to +150°C. It is typically available in a DO-201AD package. The Schottky barrier construction results in very fast switching speeds compared to standard rectifier diodes.
