SOT-23 devices marked AZY and ALG -- What are they?

[John Muchow]

I *think* I've found the information for the "ALG" marked device...
NPN switching transistor, 60Vbc, 50Vbe, DC hfe=200-400.

But, I can't find any info on the one marked "AZY". Could this be the
PNP counterpart? Both are used on a battery pack discharger.

Does anyone have a link that lists manufacturer's case markings? A
Google search for "ALG" and "AZY" only turned up info on "ALG".

Thanks!

Look on the PC board for a label, such as Q12, which might tell you if
it's a Q or D, or whatever.

Thanks!

I checked the KEC web pages but I didn't find any place where they
said that the transistor was marked AZY. Where did you find this
information? In the other followup I gave him the Marsport
crossreference site, but I didn't find this in that list. Thanks.

I got the information from my ECA xref list, but KEC has a 'search for
mark' option on their website. The datasheets refer to this marking too.

This looks like it might be the place

WOW!!
Everyone, thank you so much for the info and those great links, I
really appreciate it. Now I might actually be able to repair this
thing.

Good tip.

There was a Q in front of a two-digit number on the silkscreen layer
for both devices (and I was just going to use a general purpose
switching transistor with specs that I thought would fit), but
suddenly I realized that I didn't know if they were PNP or NPN and
that I needed a datasheet.

But, you guys came to the rescue...thanks.
