SPICE PARAMETERS (Gummel-Poon Model, Berkley-SPICE 2G.6 Syntax)

PACKAGE EQUIVALENT CIRCUIT

TRANSISTOR CHIP DATA

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).

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.
