    can anyone pls give me a replacement transistor for SS8550....this transistor cant handle a higher voltage than 5V ...so i was hoping if i could find a transistor which can handle a higher voltage than this(maybe 9V+)

    (The transistor listed in here is the transistor I have)

    A 2N2222A (NPN) or 2N2907A (PNP) should do the trick.

    It's an rc circuit i removed from a toy car...so would these replacements work fine with the other components?

    2n5401 will work nicely.

    Just get the same transistor $0.24 plus shipping. Order 10 so you have spares if it happens again.

    I've never seen a transistor for 5v max

    For radio circuit you should use the same type.

    Important is max permitted base current at which 5v never will be reached. The lowest ce breakdown I know is 20 volts for common kinds, reverse breakdown about 12v.

    You should specify which voltage you talk about

    Wow, it took a long time to get some good answers to him. We are improving around here.
