The SOT-343 package has two emitter leads. To avoid high complexity of the package equivalent circuit,
both leads are combined in one electrical connection.

For non-linear simulation:
Use transistor chip parameters in Berkeley SPICE 2G.6 syntax for all simulators.
If you need simulation of thereverse characteristics, add the diode with the
C’-E’- diode data between collector and emitter.
Simulation of package is not necessary for frequenties < 100MHz.
For higher frequencies add the wiring of package equivalent circuit around the
non-linear transistor and diode model.
Note:
This transistor is constructed in a common emitter configuration. This feature causes
an additional reverse biased diode between emitter and collector, which does not
effect normal operation.

Transistor Schematic Diagram
The common emitter configuration shows the following advantages:
Higher gain because of lower emitter inductance.
Power is dissipated via the grounded emitter leads, because the chip is mounted
on copper emitter leadframe.
Please note, that the broadest lead is the emitter lead.
The AC characteristics are verified by random sampling.
