Data Sheet
Description
The SARS01/05 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 SARS01/05-incorporated snubber circuits allow better cross regulation of multiple outputs.
The SARS01/05 can also improve power supply efficiency by partially transferring such ringing voltage into the secondary side of a power supply unit.
Features
● Improves Cross Regulation ● Reduces Noise ● Improves Efficiency
Applications
For switched-mode power supplies (SMPS) with flyback topology such as:
● White Goods ● Adaptor ● Industrial Equipment
