ECG807

ECG807: High-Drive Darlington Transistor Output Optocoupler packaging an infrared emitting diode optically coupled to a high-gain NPN silicon phototransistor Darlington pair inside a 6-pin plastic footprint frame. It functions by utilizing the massive current gain of the Darlington cascade to directly switch heavy downstream electrical loads up to 150mA across a high dielectric safety barrier, standard for driving mechanical relay coils and solenoids.
