Hello,
I've got a PC motherboard that has a 3 legged device on it - presumably a transistor, FET etc .... with the markings N1D1 on it ...
Anybody got any clues what it might be ?
Thanks, Ian

Or a voltage regulator, or a shunt-type regulator, or a general- purpose diode, or a temperature sensor, or ... ... ...

Is there a circuit reference on the PCB, eg Qnn, Dnn? Can you tell us what components are nearby?

Unfortunately enough they are all for small packages with cryptic marking.
I do have a couple of tubes with some ST Micro transistors (?) or something that I can not identify. And ST Micro itself is of no help -- they don't have their markings available from their site and 90% of their PDF datasheets don't tell you what the markings are...
My parts are in D-Pack (TO-252) and have ST logo and 3 lines of text on them:
ST(logo) CHN K922 LD338
Can anybody tell what it is?
