Description
The SARS10 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 with low noise, conduct the surge
voltage and noise into a capacitor. A series resistor, R_S , of 22 Ω
is built into the SARS10, eliminating a external component.
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.
Applications
▪ White goods appliances
▪ Audio-visual equipment
▪ Light fixtures
▪ Communication equipment
▪ Factory automation
