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 Table A and using ST Spice Library (available on 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).
