transistor markings/replacment

[Diarmuid1]

Hi,

I am having some difficulty duplicating a circuit which I have come across.  One of the components, is a transitor and is marked in the following way:

• 1) It has 205 M8 on the top
  2) and 206 j174 on the face side

I have tried running various combonations of the above markings through google, rapid electronics and google to no effect.  Does anyone know what transistor this is, or even what type it is?

Also, when replacing a transistor, is it likely to damage/break/stop the opperation of the circuit?

Thanks for all your help

Hi,

What size of case is it? Can it possibly be an 2SJ174 - P channel MosFet 60V 20A 75W? :

The case is pretty much the normal size, in that it is like all the other transistors  I have seen.  I dont know the exact sizes, but if you could tell me what measurments I need, I could probably find them.

Thanks

The 2SJ174 has a TO220 case.

I dont think it is that one, as the one I have is in a case with one round side and one flat side.

I am sorry but it’s very hard to identify your component from such a vague description. A way to try is if you have a digital camera with a macro lens you could post some pictures.

Is your circit a transmiter or voltage reg?  P.S. if I have trouble finding a comp.
I am looking for. I go down to the local t.v. repair shop and look in his parts
list book. Just about everything you could need you can find in there.
