What is a Zero Crossing Detector?
A Zero Crossing Detector is an essential circuit widely used in signal processing and electronics to detect when an AC signal crosses zero volts, transitioning betwe
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.
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.
