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.

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.

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.
