150 V Schottky — margin for high-rail OR-ing and flyback
The STPS20150CG-TR is a dual common-cathode Schottky rectifier from STMicroelectronics, rated for 150 V reverse voltage and 10 A average rectified current per diode.
Forward voltage is specified at 920 mV maximum at 10 A, which is typical for a 150 V Schottky — the higher blocking voltage trades off against a slightly higher Vf compared to a lower-voltage part.
