Description
The SFH6943A is a four channel mini-optocoupler
suitable for high density packaged PCB application. It
has a minimum of 1768 V_RMS isolation from input to
output. The device consists of four phototransistors
as detectors. Each channel is individually controlled.
The optocoupler is housed in a SOT-223/10 package.
All the cathodes of the input LEDs and all the collec-
tors of the output transistors are common enabling a
pin count reduction from 16 pins to 10 pins-a signifi-
cant space savings as compared to four channels that
are electrically isolated individually.
