Damaged Bipolar Diode

[liorillusion]

Guys i really need your help

I took the machine to my electronics guy and he identifies the problem as follows:

The more serious problem is that he says the BIpolar diode also got damaged...he said that he tried to look for it with his usual supplier but he couldn't find it according the (Japanese) serial number on the BIpolar diode...the serial number on the BIpolar is: SC550B my question is do you know what kind of BIpolar he should look for or what is the parallel BiPolar Diode i should look for? or maybe its not diode?

maybe this one? http://pdf1.alldatasheet.com/datasheet-pdf/view/226009/BILIN/VR60.html

Thank you very much for your help!

Ive attached some pictures of the damaged component - any help will be appreciated!

hi there
welcome to the forums

that link took us to dozens of components
was there one in that huge list that you were specifically considering ?

no but some one told me this
"Here are some you have a chance of ordering over the internet.. or getting where you are at an electronics store. They have them at the store near me. (But then i live in ye-old Silicon Valley...)

The #4947 has around 40v breakdown voltage, which that SC550B has in its spec."

this is like my sc550b? and you know what this the part ineed for this? maybe other?
and i fix the url on top

thank you!

No you can't use that since it is unipolar. The 4947 was not listed any more, so I suppose it is obsolete.

Farnell has some good ones. P6KE43CA from either Littelfuse or Fairchild Semi, should be in your ballpark. Farnell number 1827664 or 1467628,
