What this Schottky diode brings to the board
The STMicroelectronics STPS1045B-TR is a 45 V, 10 A Schottky rectifier in a DPAK surface-mount package.
The 45 V reverse voltage (Vr) is the maximum DC blocking voltage the diode can withstand.
10 A average current — sizing the load budget
The 10 A average rectified current (Io) is the continuous DC load the diode can handle with proper heatsinking.
630 mV forward drop at 10 A — the efficiency number
At 10 A forward current the typical forward voltage is 630 mV.
