Anyone familiar with an NPN SMD transistor with the marking "1RM" ?

I'll ship a free PCB to whoever identifies it first.    ;D

EDIT: Identified, thanks!

Best guess is MMBT5089. That is 1R. Not sure what the M designates, but the second letter on other transistors is a country of origin code.

Thanks man, 5089 sounds about right for this circuit.

PM me your info and I'll ship you a board as soon as I get them.
