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
· Simulation of package is not necessary for frequencies < 100MHz.
Note:
· This transistor is constructed in a common emitter configuration. This feature causes
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
Please note, that the broadest lead is the emitter lead.
