Optocoupler
Solid State Relay - Basics, Working, Types and Applications of SSR
What is Solid State Relay?
A solid state relay or an SSR is an electronic switching device which can be controlled by applying an external voltage to the control terminals.
TLP521 Series Optocoupler with GaAs IR-LED & Photo-Transistor
The Toshiba TLP521-1 consists of a photo-transistor optically coupled to a gallium arsenide infrared emitter diode.
EL4N35 Optocoupler IC
EL4N35 Phototransistor Optocoupler IC comes as a dual inline package and has 6 pins.
MOC3063 Zero Cross Triac Optocoupler/Opto-Isolator IC
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 Optocoupler/Phototransistor IC
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.
What is Optocoupler and How it works?
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.
EL357 Optocoupler – Transistor Output
EL357 is a DC Input based, Phototransistor Output Optocoupler that is the exact equivalent of popular PC817 optocoupler. It uses an infrared
