    5401DM what a transistor. what it can be replaced is controlled by the ignition coil

    Hello
    I was able to match interchangeably, but I had to put in another three passive electronic components.

    This is not a transistor

    proposes to buy a computer on the back of a notebook and desolder such a tip on the occasion you will have one more on stock :D
    I did it.

    This is mosfet. I used irf840 but to trigger you had to add an amplifier from the transistor because the original is triggered with 5 va irf needs probably 7. After this operation everything is ok. But you have to choose a good transistor for the amplifier as far as I remember pnp. Bartek

    Jureczku must come because they did a few kilometers and nothing happens to them. I have substitutes at a good price but I have to test them and some time is missing. The table works but I have to let it in the car ...

    In fact, the abundance of us with us abundance .... what endings I tested on the table for several hours and was ok. Temperature in the norm only that in the engine compartment there is no such working conditions ....

    Hello all.
    Let some of you tell me how to get this original driverrek from the switchboard.
    It looks like soldered entirely on tin to the main board.

    And such a large resistance solder that I use to solder the stator wires from alternators. He has something like 150 watts.

    I soldered the feet long ago with an ordinary small soldering iron. Only the radiator from the tile has left me.

    I bought a different version of the eecV central unit, but that's where the driver is called 5401 But the tip of GE was probably tomorrow I will check more carefully. And it had covers as long as I well mark TO-132 with a badge with a hole. I mounted on cables and the car was a guitar. Drivrek screwed through a silicone pad and pressed it with a clip screwed on by a screw.

    This is called PROFI repair .....

    bohun555 can you write like the tests of your replacements?
