Package equivalent circuit
Figure 2.
In order to avoid high complexity of the package equivalent circuit, the two emitter leads of
SOT-343 package are combined in one electrical connection.
For more accuracy simulation in saturation region:
Adding the 5 spice parameters showed in
request) you can achieve a more accuracy simulation in the saturation region. ST spice
library is compatible with following simulators: ELDO MENTOR (any version), SPECTRE
CADENCE (any version), ADS (version 2001 only).
