hello everybody
when i was looking for something about transistor i saw this group and
i have just joined the group.
i live in turkey and work for company which detects the faulties on
electronics boards and fix them.
on a board we determined a fauly transistor on which it writes only
'RE'. i couldnt find it yet. does anyone know what kind of transistor
it is or another transistor that is equivalent of this transistor?
if someone helps me i will be really pleased.
thanks

I'm afraid that just "RE" won't be enough. Is there nothing else at all ?

Graham is right -- you don't have enough information to do anything,
I'm afraid. You haven't even mentioned the circuit board you're
trying to fix. Just throwing in a random replacement could result in
damaging other components.

Try talking to other people at your company, or contact the
manufacturer of the board (if they'll talk with you).

If you know someone who is knowledgeable about electronics, they can
take a look at the circuit and possibly hazard an educated guess
fairly quickly, particularly if the transistor is doing something
simple and/or obvious like turning on a relay.

Worse comes to worst, you can try having somebody reverse engineer
enough of the board to try and find the transistor's function, and
they can suggest a replacement.

Best of luck!

As was said by others, 're' does not say
much about the transistor. Can you tell
from the circuit whether it's NPN, PNP
FET or something else?

What you can do, is try to determine what
its function is in the circuit. Is it in
a high-frequency radio section? Is it
used in an audio pre-amp stage? Is it
used in a high-power amplifier output?

Does it switch on a relay, or send a
signal to a logic gate?

What is the source voltage for this
section of the circuit? This will tell
you what type of Vce your replacement
device will need.

If it's not high-frequency or high-power,
you might get away with using a general-
purpose small-signal transistor from your
junk box.

** Groper alert !

when i was looking for something about transistor i saw this group and
i have just joined the group.
i live in turkey and work for company which detects the faultiest on
electronics boards and fix them.

** So it's a tiny SMD transistor right ??

You need to ask the maker of the PCB what it is, since " RE" is not a part
number by only a reference code used by the maker of the transistor.


BTW

"..... detects the faultiest"

- love it !!

You didn't "join" a group - you posted via Google to Usenet. Usenet
is not Google; Google is not Usenet.

You really need more information to start replacing parts on circuit
boards - a schematic diagram would be a good start. Failing that,
measuring the part on a good board or a part with the same marking may
work - if you have the knowledge to check the part to find out what it
is.

Could be anything bipolar, JFET, MOSFET, or dual diode, or integrated
circuit. Know what it does, and you could make an informed guess as
to what would replace it.

If it is a surface mount device (as Phil suggested) then it may be a
2SC3357 which has a marking of RE.

thank you all for trying to help me. as randy day asked whether it
switched on a relay... yes i think the component is about relay. also
there is a diode which is three-pin component near the component i
have beeen talking about. this diode also was broken and A9 was marked
on it but we could find out what kind of it is and then we replaced it
with the new one. the transistor is marked only with 'RE'. some says
this may not be a transistor but on the board the reference for this
component is tr6. tr propably stands for transistor, i think.
ross herbert asked if it was surface mount device like phil did. yes
it is. thank you for advice, i will now focus on what you say it may
be a 2SC3357
thank you all again

Is there any need for this sort of thing?
If you have nothing to say but abuse, why post?
If you can't restrain yourself, perhaps you should
get your medication adjusted? jack

How is it taking out the rubbish?
The guy asked a question.
It was well answered (not by you BTW)
(And I noted your ridicule of this
non-native English speaker's English.)
He then thanked everyone for helping him,
and you had to then come in
with this abusive, empty post.
Have you not the wit to see how useless you can be?

** The OP is a nut case troll - you stupid ASS !!

He is the rubbish !!!!


The guy asked a question.



** Not one about electronics basics.

Nor one that made any sense.

Nor one he was prepared to take good advice on.


It was well answered (not by you BTW)


** It was EXTREMELY well and CORRECTLY answered

by me - you fucking, fuckwit ASSHOLE !!!!!!!!!!!!

He then thanked everyone for helping him,


** The OP is a fucking mental retard.

Either he is a damn liar OR he works in a sheltered workshop for retards.

The retards are checking junk PCBs to keep them out of trouble.

That were YOU are posting from too


- **** HEAD ??

hey man what the are you talking about?

Welcome to sci.electronics.basics.

As a poster in this group, you are allowed (if you're lucky) ONE, and
only one, useful response from Phil.

I see that you have already received one useful response from him.
Congratulations on being among the lucky few! However be warned that
further attempts at useful discussions with Phil are futile, as you
are now finding out.

Best to move on, ignore him, and ask for advice from other people in
here.

Again, welcome.

thank you

by the way i have made lots of search on net and i think i got what i
want.
the code RE i have been talking about is a smd code of a compenents. i
was thinking it was the part number of the compenent so i focused on
that while searching but this is not the way i should. RE is a smd
code and while searching this kind of compenents we should look for it
on smd code books so we can get the result more easily.
thank you all againg except phil even he tried to help at first.
