    PC817B

    Description

    The 817 series of devices each consist of an infrared

    emitting diodes, optically coupled to a phototransistor detector

    encapsulated with green compound.The devices are in a 4-pin

    DIP package and available in wide-lead spacing and SMD option.


    Features

    ◆  Current transfer ratio(CTR: 50~600% at IF =5mA, VCE =5V)

    ◆  High isolation voltage between inputand output (Viso=5000 V rms )

    ◆  Creepage distance >7.62 mm.

    ◆  Operating temperature up to +110℃

    ◆  Compact small outline package

    ◆  Pb free and RoHS compliant. 

     

    Applications

    ◆  Programmable controllers.

    ◆  System appliances, measuring instruments.

    ◆  Telecommunication equipments.

    ◆  Home appliances, such as fan heaters, etc.

    ◆  Signal transmission between circuits of different potentials and impedances.
