KT1210 Series
4PIN LSOP PHOTODARLINGTON
PHOTOCOUPLER
Description
The KT1210 series consist of a photo darlington
optically coupled to a gallium arsenide infrared-emitting
diode in a 4 pin LSOP wide body package. It features a
high current transfer ratio, low coupling capacitance and
high isolation voltage.
