put finger to keyboard and composed:
Body marked as follows
FPN
4249
EBC
has blue paint dab on back. It's pretty clear what the EBC marking means.
I know it is PNP from the schematic which says type is TO203 but I don't
recognise that either.
My old "Towers International Transistor Selector" lists the PN4249:
PNP
TO92
L14 pinout (EBC)
Vcb=60V
Vce=60V
Veb=5V
Ic=100mA
Tj=150C
Ptot=600mW in free air
ftmin=100MHz
Cob=5pF
hfe=100min
hfe_bias=100uA
use=ALN (audio, low current, low noise)
manf=NAT (National Semiconductor)
EUR equiv=BC204
USA equiv=2N4249
Towers attributes the PN prefix to Newmarket:
PN = Newmarket, plastic version of equivalent '2N' number
The 2N4249 is listed as having been manufactured by "FCU" which is
Fairchild Semiconductor.
