Package equivalent circuit

Note:

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 8 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).
