Description
The SARS02 is an 800 V silicon diode designed especially for
use in high-efficiency snubber circuits. This diode can sustain
a high voltage with low loss, with low-noise rectification.
To suppress surge voltage, conduct the surge voltage and
noise into a capacitor via a series resistor, R_S . Then allow the
capacitor to discharge the energy into power supply line with
the regenerative circuit operation, shown below in the typical
application circuit schematic.
