SARS05 fiche technique
Auxiliary Switch Diode for Snubber
SARS01/02/05/10
Data Sheet
Description
SARS is the auxiliary switch diode for snubber circuit,
used in the primary side clamp snubber circuit of
switched-mode power supplies with fly back topology.
Since the ringing voltage at turning off the power
MOSFET is more reduced by the clamp snubber circuit
using SARS, the cross regulation of multi-outputs is
improved. Since some energy of the ringing is
transferred to the secondary side, the power supply
efficiency can be improved.
