"LF" SMD code

[Kasamiko]

Hi mate..
I check some website of SMD codebook like this one:
http://www.tkb-4u.com/code/smdcode/smdcodeL.php
but can't find any code for this devices.
It's a 3 terminal SOT-23 transistor with this marking "LF".
Any info might help.

This is a package outline for SOT-23 package

LF = NPN if my German is correct check here!

Honoured colleagues,

I look for the type names and the manufacturer of two bipolar
transistors in the SOT-23-Gehaeuse. The construction unit codes read:

"MF" on a PNP transistor "LF" on a NPN transistor

The Pinning is the equivalent BC848/858. Both transistors are from the same manufacturer, since the
construction unit surface and the stempeldruck are perfectly
identical.

Who can help me here? Thank you in advance for each support.

With kind regards


 Now here is the Datasheet for the transistor he mentioned.

Thanks John..I'll try that device and post the result here.
Thanks again.
