The Toshiba TLP521-1 consists of a photo-transistor optically coupled to a gallium arsenide infrared emitter diode.

EL4N35 Phototransistor Optocoupler IC comes as a dual inline package and has 6 pins.

MOC3063 IC is a 6 pin I/O Optocoupler/Optoisolator with an integrated gallium arsenide Infrared emitting diode optically coupled to a TRIAC output with a Zero-crossing circuit. The IC can provide optical isolation to devices operating at 115/240 VAC lines.

EL817C IC is a popular optocoupler IC. The IC like any other optocoupler consists of an infrared emitting diode which is optically coupled to a phototransistor detector.  

If you’ve ever taken apart any phone charger or a switching power supply, you’ll find some tiny black IC packages with an unusual number of pins, mostly four or six, both in SMD and through-hole variants.
