Title: Help with part ID. Can't find any data.
Post by: BillyJ on January 05, 2004, 01:56:35 AM
This is the odd thing. They look just like a si trannie but the the middle leg is cut very short but it is on tape so that doesn't jive.
Missed that before I left the surplus house.  :oops:
Searched and no luck.
The numbers are P31008
Second line:          A70
Third:                     K3

Any info appreciated.
Thanks!

what i do to find parts probably isn't the best but i got to the nte site and search the part numbers to see if they have a substitute and a data sheet for the part number i have... they are usually pretty close but sometimes i can't find any info... good luck...

What I do in these situations, is to stick it in a HFe test socet of a multimeter, if you can find one way around that has gain, then you know it is a transistor! That number doesn't look like any normal transistor series, but it could still be one.
