    i have a bunch of parts that look like power transistors but i'm not sure
    i look up using the #s online but yet to find some

    hswc
    2scf4242
    gft


    sec
    604
    c2335-r
    the priveus ones were on heatsinks so i'm thnking shockety or vreg not sure though

    another looks like an old metal case transistor. has A23, 380-3, 449 on it. a saw a pic of a traic that looked just like this too though. the lastic holder has a B and an E by 2 terminals. and it has a resistor between these then the E terminal has a ceramic cap and a part that apears to be a diode going to a screw holding it on. what do you think this is?
    i was guesing transitor but where's the colector? or is the case th colector.

    i pull these type parts alot and i'm getting tired of having to google every one. i try to use all data sheets but they only have about 60% of them.
    do the numbers mean anything. E.G. 111-444 mean it is a transistor. then 555-888 is a voltage vegulator. or do i just need to look them up?

    Could it be:

    2sc4242
    2sc2335

    ?

    These you find on alldatasheets.com

    Can you post a picture of the last one you were talking about?
