I got a transistor, which is smd, and it has the marking of DF then
under it RK (the K has a dot on top of it).
Could you tell me the specs of the device so it could order some of
them or a similar device?

Thanks for any help in advance.........

I am looking for a type of Motorola transistor with marking 5_581.
Will be very thankful for any assistance.

Hallo

the problem is, that codes are not standardized. When you dont know the
manufactorer of the device, it is hard to find out the type.

I got two transistors, which are smd, and they have the marking of E:5
 & E:2 Could you tell me the specs of the devices so it could order
Some of them or a similar device?

Dear Madame/Sir,

I am having a SMD piece (probable a transistor), with broken contacts
and I would like to replace it with something similar. There is a code
written on the piece  A006, but I didn't manage to identify it. Thus,
I would like to ask to help me identify the piece and find a possible
substitute.  Please write me at this e-mail address.

Thank you.

Yours,

If it is necessary to define the type SMD semiconductors on its code
of the marking (marking code, top mark) - visit the site   (no www !)

http://users.zebratelecom.ru/~smd_marking

The having read article "rules of the marking" you get the full
presentation,
as this it is necessary to do, and as it is impossible.
You will Find the useful references to sites for searching for of the
type on code.
You will Be able gratis lood 4500 codes in PDF file compressed before
120KB.
You will learn of new version CD on marking codes and their searching
for.
In the world exists beside 150 thousand marking codes for approximately
two
hundred companies.
There is  the catalog on 73000 codes (109 companies of the world) in
Russia now.
In principle, exactly for Your code possible: - find type of SMD, with
probability
of the positive result more than 50%.
If it is necessary to search for often and much - needs special
catalogue on CD.
Then searching for of the type on code - real and quickly.  Such
catalog - not only
searching for of the code and type, this is Your GUIDE in the world of
modern SMD.
