DESCRIPTION
The SFH6941 is a four channel mini-optocoupler suit-
able for high density packaged PCB application. It
has a minimum of 2500 VDC isolation from input to
output. The device consists of four phototransistors as
detectors. Each channel is individually controlled. The
optocoupler is housed in a SOT223 package. All the
cathodes of the input LEDs and all the collectors of
the output transistors are commoned enabling a pin
count reduction from 16 pins to 10 pinsâa signiï¬cant
space savings as compared to four channels that are
electrically isolated individually.
