<< HI there everyone, I've been pulling my hair out for the last few days,
 as
 we have several products designed to use a ST/SGS-Thompson part that
 appears to have
 gone obsolete since we last purchased any.

 Only we didn't know & are now searching for any of these that are going
 spare anywhere in the world.

 The part is a "Transil"  Bi-directional surge protector type SM4T36CA.
 Any equivalent parts that have been suggested have a different footprint
 (this part uses SOD6.).

 We have searched the www & exhausted all our suppliers, so now I'm
 reduced to begging on the streets (well TechNet at least!).

 Can anyone point me in the right direction?

Hi Matthew!

I did a "Dogpile" search and found this:

http://us.st.com/stonline/index.htm

At the upper left corner in the search box type in: SM4T36CA  and it'll take
you to a page that has the data sheet for the part in *.PDF format. But when
you said it was obsoleted, I called their US office and you are right, it is
obsoleted...bummer.

Can you use a 600W part? The SM6T36CA is the same part, but 600W...it goes on
the same footprint as the SM4T36CA...sorry couldn't be more help...
