Saturation voltage.

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).HAO et al.: ANALYTICAL EXPRESSION FOR DRAIN SATURATION VOLTAGE OF POLY-Si TFTs 359 TABLE I V Dsat (IN VOLTS)CALCULATEDBASED ON(10)–(12) ARE COMPARED TO EXPERIMENTALLYEXTRACTEDV Dsat AT VARIOUS Vg, FOR BOTH n-AND p-TYPE POLY-Si TFTs BY EITHER LOW OR HIGH TEMPERATUREPROCESS In …When the primary winding of a transformer is subjected to excessive voltage, the core flux can reach saturation during the peak moments of the AC waveform.

A transistor in saturation mode acts like a short circuit between collector and emitter. In saturation mode both of the “diodes” in the transistor are forward biased. That means VBE must be greater than 0, and so must VBC. In other words, VB must be higher than both VE and VC.

Feb 24, 2019 · At what voltage maximum saturation current is present? Naturally, this region is referred to as the saturation region. The drain current in saturation is derived from the linear region current shown in equation 3.18, which is a parabola with a maximum occurring at V D , sat given by: (3.22) Overcoming the threshold voltage is much easier around the source because the source is at a lower potential than the drain. Now it becomes the same story as the JFET - if the drain voltage rises then the pinch-off is more pronounced and current remains largely constant.

Comparing Eqs. 4-40, 4-41 and 4-42 it can be noted that the additional harmonic voltage term has the opposite phase sequence than that of the applied current. For example, if the applied current of order h = 7 has a positive-phase sequence, then the additional harmonic voltage component has the order 5 with a negative-phase sequence.This is the usual situation for a balanced system.

That means there will always be a voltage drop across the transistor. Taking the typical forward voltage of 1.7V for a red LED, a 5V supply, and a 75 ohm resistor, I get a current of 44 mA.
