An insulated gate bipolar transistor is simply turned “ON” or “OFF” by activating and deactivating its Gate terminal. Applying a positive input voltage signal across the Gate and the Emitter will keep the device in its “ON” state, while making the input gate signal zero or slightly negative will cause it to turn “OFF” in much the same way as a bipolar transistor …What happens when there's too much voltage?

That's just a definition. Above the saturation region is the active region where the transistor acts like a good current source, or current amplifier. There is no "one" saturation voltage, but the concept of saturation voltage is still useful to designers, and that saturation voltage is never at the knee, for the reasons I mentioned above.Electronically, saturation is defined as the point where an amplifier cannot amplify any more, it has run out of operating range. The transistor Q1 is amplifying the current from Q2, drawing load current in the inductor and pulling the voltage down; the voltage can't pull any further than saturation. (Conversely, when Q2 turns off, Q1 also ...

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).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.

I believe I understand transistor saturation, but whats the difference between Collector-Emitter Saturation and Base-Emitter Saturation? BJT saturation depends on the CB junction no longer being reverse polarized and the Ic current rise and voltage drop of Vce less than Vbe. This apparent forward conduction of collector-base also reduces …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)13. In the photoelectric effect, photons incident on the cathode cause the emission of electrons. Assuming there is a sufficient electric field, these electrons will make their way across to the anode, contributing current. For simplicity, let's assume every photon generates a photo-electron. Then if N N photons per second hit the cathode, the ...As the final stage of a pseudo-Darlington, the PNP is never in heavy saturation and its voltage drop is higher than what could be obtained from the same PNP in heavy saturation.

The E-C voltage drop in saturation is dependent on the current for a given ratio of base current to collector current. Here is the typical behavior of a 2N4401:. With 100mA of collector current you'll typically see a ~0.14V drop if you drive the base with 10mA.Manufacturers will specify the maximum voltage drop of a transistor at saturation, both between the collector and emitter and also between base and emitter (forward voltage drop of that PN junction). Collector-emitter voltage drop at saturation is generally expected to be 0.3 volts or less, but this figure is, of course, dependent on the specific type of transistor.
