The TSFP-4 package has two emitter leads. To avoid high complexity fo the package equivalent circuit, both leads are combined in one electrical connection. RLXI are series resistors for the inductances LXI and Kxa-by are the coupling coefficients between the inductances Lax and Lyb. The referencepin for the couple ports are B, E, C, B`, E`, C

For non-linear simulation:
· Use transistor chip parameters in Berkeley SPICE 2G.6 syntax for all simulators. · If you need simulation of the reverse characteristics, add the diode with the C'-E'- diode data between collector and emitter. · Simulation of package is not necessary for frequencies < 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.
