Yet another component to identify...

[drsmith]

I've got an SMD device I can't identify. It appears to be a
transistor or mosfet in a sc-59 package(the package code is from
onsemi.com and the physical package measures 2mm wide x 1.3mm x 1.0mm
high) The marking code is HR and has a dot pattern following it(bad
ascii art follows):

xx
x

Other transistors on the board with similar packages and markings are
easily looked up. All appear to be made by On Semiconductors. I'll
try to post a link to a photo of the device if anyone's interested,
but I'm not sure my camera is capable of producing a photo of such a
small device that would be readable.

I've spent quite some time searching their datasheets for this marking
code, but can't seem to locate it. It isn't otherwise listed in the
other web-based cross references I've checked. Any help would be
greatly appreciated. Thanks.

A lot of people expect their digital camera to focus close up. But that
often doesn't happen. For this problem, you can put a small magnifying
glass in front of the lens, and try to get closer to the object. With
the right magnifying glass, you can get within a foot or less, maybe a
few inches, and get a good picture.

I didn't think that would work - a magnifying glass is intended to
create a projection for a person's eyes instead of a flat digital
sensor. I may give it a shot, though and see how it turns out. I
don't otherwise have any diopters for the digital camera - I'd
otherwise have to use a 35mm camera, get it developed, scanned, etc.

Thanks for the tip.

I get very good results photographing SMD mounting problems with a 4x
or 10x loupe held to the lens of my digital camera (Toshiba PDR-M100,
old and non-exotic).

Magnifying glasses are *not* ground with a variable focal length
across their surface to try and match the radius of curvature of your
retina

I like that answer. I tried photographing the component using a canon
S45 and my 35mm diopters(couldn't find the magifying glass and a loupe
would have interfered with the flash), but the laws of physics aren't
on my side on this one. As you get closer to the component, the depth
of field gets very, very thin. The automatic focus was a complete
crap shoot as to where it would wind up and manually focusing wasn't
really any easier.

I could get good images of the other nearby components and their
markings, but the marking on this transistor was particularly faint
which made it even more challenging.

Thanks to everyone for the help - I'm off to go find the datasheet.
