    SMD IC identification

    i have on PCB any SMD IC with this code

    1. size any as MSO8
    51TI
    R5R


    2.size any as SOT23-5
    WJ=U58

    3 size any as DPY23-6
    312S

    4.size very small 2x3pin
    TAR

    5. size very small 2x4pin
    CT2R

    Re: SMD IC identification

    Hi,

    What about photos?
    Manufacturer logo?
    Information about the application? What does it do? Is it RF, controller board, power circuit?

    Re: SMD IC identification

    I will restore my old theme.

    I still looking

    SMD marked as 312S (above the three is a dot)
    function is simple switched 5V 500mA max from input pin 5 to output pin 2 , switchung drive MCU over diode marked as to P3_1 any as PNP transistor but have 6 pin case and any functionalit on pin 3

    Click image for larger version.

    2. case marked as
    1TI
    R5R
    size any as MSO8
    it's a dual opamp on +5V any as LM358 but I would like to know the exact type

    Thanks

    Re: SMD IC identification

    Hi,

    1) I doubt it looking at your description and the pinout..., Series PVT312PbF photovoltaic relay, PVT312.

    2) You'd need to trawl SMD code webs and pdfs and hope to be fortunate and/or see if the code represents a manufacturer name.

    Re: SMD IC identification

    1. PVT312 ralay is in 6pin DIP and size equivalent SMD case, but my IC is in SMD case of size SOT23-6 . Relay on 250V in SOT23-6 is nonsense, because of insulation distances.
    2. Yes I look on SMD code book 2014 and other known to me SMD code source but the result is big zero

    - - - Updated - - -

    312S wil be any High-Side Load Switch but what have input and output pin on center pin 2 and 5?
