Need help identifying part

[.]

Hi all,

I came across a part that I can't identify. The manufacturer is National
Semiconductor and it's a TO-92 case style with three leads. The number on
the device is NB121EI. Any help identifying this part would be appreciated.

It is fairly unremarkable, low-power, silicon PNP device.

NB121EI (Si, PNP)
-----------------
Vceo(max) = 35V
Ic(max) = 100mA
PD(max) = 600mW
hFE = 180
fT = 100MHz
Cob = 3.0pF
Case Style = TO-92 (base in the middle)
