I have a smd transistor (SOT23 package) with the marking 72kCB. I checked out a number of websites, including the smd Cook Book and there is no reference for it. Does anyone know what part number this is?
Thanks in advance.

After several hours on Google, I couldn't find any informations on a smd transistor marked "NHR8", in SOT-323 (or 23) package.
Someone's got some specs or type for this transistor ?

I have a PCB which requires smd transistors in SOT23 package but the problem is the pin configuration. Standard SOT23 transistor has the following configuration:
1 = B
2 = E
1 = E
2 = B
Does someone know of SOT23 npn transistors with this pin configuration?

i took some smd transistor like devices off a board of some broken VCR's, the markings on them were originally blacked out, removing of black paint on top of them revealed these:
ZS (on most of them)
BS (on a few)
BQ (on one or two)
just two letters, other than those two letters, there seems to be no room for any other markings.

Note the lower Collector Power Dissipation 625 vs 310mW due to the smd package.
