Saturation voltage.

Saturation velocity is the maximum velocity a charge carrier in a semiconductor, generally an electron, attains in the presence of very high electric fields. When this happens, the …A Schottky diode is integrated into the transistor from base to collector. When the collector gets low when it's nearly in saturation, it steals base current which keeps the transistor just at the edge of saturation. The on state voltage will be a little higher since the transistor isn't fully saturated.IC=beta (Vcc-Vbe)/RB and Ic=Is*exp [ (VBE/VT)-1]. (For normal operation in the active mode the exponential expression is much larger than "1" - hence, we can neglect the "1"). An exact solution is possible (graphical solution) if we plot both functions Ic=f (VBE). The point where both curves meet is the actual operating point (Ic and VBE).NSS20200DMT www.onsemi.com 2 Table 1.
