The SARS is an auxiliary switch diode especially designed for snubber circuits, which are used in the primary sides of flyback switched-mode power supplies.
Being capable of reducing the ringing voltage generated at power MOSFET turn-off, the SARS-incorporated snubber circuits allow better cross regulation of multiple outputs.
The SARS can also improve power supply efficiency by partially transferring such ringing voltage into the secondary side of a power supply unit.
