Hi, i'm designing a NIMH battery charger with Ds2711 that requires a pnp low saturation transistor, FCX718.
I can't find this where I live. Anyone know an equivalent for this transistor? Tried google but didn't help much.
The datasheet for this transistor is here:

AC equivalent circuit is used in ac analysis. For example, the MOS transistor is not linear, if we want to analyze it, we must use linear equivalent circuit . But the dc equivalent circuit and ac equivalent circuit of MOS transistor are not same. So we use them in different analysis.

The transistor has collector-base capacitance. Remember that I=C*dv/dt. So, if your collector voltage has a slew rate of 100V/usec, and is a true ramp, and your transistor has Ccb=5pF, you will see a flat-topped pulse of 500uA each time the collector voltage switches positive, and -500uA for each negative transition. The pulse width will equal the

1. The input impedance of a MOS transistor is near infinity near DC. As you go up in frequency it looks like a capacitor. Going further up there is a real part.
2. In your simulator (or in your breadboard use a current probe) take the ratio of the gate AC voltage to the gate AC current.

The thing is like this, the process of amplification
happens because of the carriers reach collector
of the transistors from the emitter. If we keep the
arrangement of the back to back diodes this phenomenon will not occur and hence the one you
are refering is a MODEL not the physical reality.

But width stay contant!
