FOD3180 is a MOSFET Gate Driver Optocoupler introduced by Fairchild Semiconductors basically used for the isolation of two circuits. It is a MOSFET Optocoupler which has three parts i.e.a AlGaAs Infrared emitting diode, output power transistors, and a CMOS detector which functions by sensing the infrared light. Further, it offers a high switching speed, low … Read more
Optocouplers or Optoisolators are mainly used for the electrical isolation between two circuits just using the light. SFH620A is an Optocoupler that has two parts i.e., two GaAs Infrared emitting diodes and a phototransistor, which functions by sensing the infrared light. It offers a high current transfer ratio, low coupling capacitance, and high isolation voltage … Read more

MOC3041 is an optocoupler but unlike other optoisolators, it has a special feature of zero-crossing based switching. It is based on zero-crossing. MOC304X series also used to operate the external TRIACS, SSR, and MOSFETS. MOC3041 is mostly used to control AC load switching by automatically detecting the zero cross but it has internal TRIAC which … Read more
MOC3021 is a non-zero crossing based optoisolator consists of gallium arsenide infrared emitting diodes, optically coupled to a silicon-based triac. Optocoupler has multiple types and every type has almost the same operating functionality, but sometimes its internal structure makes it different from another optocoupler. There is also a TRIAC based optocoupler known as MOC3021. It … Read more
PC817 is an optoisolator consists of an infrared diode and phototransistor. In electric circuits, we use mostly filters to remove noise. The circuit based on the capacitor and resistor always removes the noise from the incoming signal but the value capacitor and resistor always depend on the incoming signal. This circuit is only applicable where … Read more
