4N35 Optocoupler 6 Pin DIP in Pakistan
Original price was: ₨40.₨30Current price is: ₨30.4N35 is an optocoupler IC in which an infrared emitter diode drives a phototransistor. They are also known as optoisolators since they separate two circuits optically. These are used to couple two circuits without any ohmic contact. They allow one of the circuits to switch another one while they are completely separate. The first circuit is connected to IR diode while the other circuit with the phototransistor.
PC817 Optocoupler
₨12PC817 is your standard optocoupler. Use this IC to isolate two parts of a circuit. Isolation prevents ground loops and prevents trasmission of unwanted noise.Input LED has a forward voltage of 1.2V and a forward crrent fof 50mA. Please use a current limiting resistor as not to blow out the input LED. requency depends on the pull up resistor you use on the output transistor.
Thyristor Driver MOC3021 in Pakistan
₨40The MOC3021/3020 Series consists of Gallium Arsenide infrared emitting diodes, optically coupled to a silicon bilateral switch. To order devices that are tested and marked per VDE 0884 requirements, the suffix ”V” must be included at end of part number. VDE 0884 is a test option. They are designed for applications requiring isolated triac triggering.
