WebJan 9, 2024 · 1. The current gain ( β, h F E, and/or h f e) varies widely over devices within a single family, let alone across many families. And it's also a function of temperature (and time.) The best one can do is speak in terms of being within a "ballpark" (some factor that … WebJun 24, 2024 · That linearized behavior can be modeled with the Hybrid-Pi model, it is an approximation of how the BJT behaves when biased at a certain I C. So the model is linear and would work perfectly well if you make apply an input signal of 1000 Volts! But that's unrealistic and not what the model is intended for.
