    Thread Starter AAC Fanatic!

    Part no. labelled is CA 42 or GA 42
    I think it is the later.

    Text is on left side and no is on right side.

    It's a SOT-89 package.

    Part is used as a relay driver in car AC Controller. Relay is used for the AC fan and compressor on off.

    I am sure it's a NPN with a Diode as there are identical ones in it. I replaced it with a BD139 and a 1N4007.

    I need to source the original part. My SMD datasheets shows nothing.

    Any one got any idea on the Exact part no ?
