IGBT collector-to-emitter saturation voltage, denoted as V CE_sat, is the voltage drop across the collector and emitter terminals of an IGBT when nominal current is flowing through it. Various factors affect the voltage drop, such as the operating temperature, current level, and characteristics of the particular IGBT used.In this case, the saturation voltage of a low side NPN transistor isn't a big deal. With only 1.2 mA collector current, you can easily run it well into saturation. 200 mV is a typical value of saturation voltage in a case like that. Even if it is as high as 500 mV, you can easily design for that just be lowering the resistor values.For the LED to light up properly, I assumed a forward current of 70mA and a voltage drop of 1.3V.

Switch efficiency is about 85% and base drive requirements are likely under 10mA 10 mA. Now look at the bottom diagram.This assists in easing the voltage stress. With time, the open circuit voltage will probably negotiate to between 3.70V and 3.90V/cell. Remember that a Li-ion battery which has acquired a completely saturated charge keeps the voltage higher for a extended than one which hasn't attained a saturation charge.According to wikipedia, the MOSFET is in saturation when V (GS) > V (TH) and V (DS) > V (GS) - V (TH). That is correct. If I slowly increase the gate voltage starting from 0, the MOSFET remains off. The LED starts conducting a small amount of current when the gate voltage is around 2.5V or so. Saturation occurs when increasing base current does not reduce collector voltage. as such it s depedant to some extent on what the load is, Depending on the degree of precision needed and what you're trying to do you can use different approximations for saturation voltage.৩ জুন, ২০০৯ ...

So the saturation drain-source voltage is Vds=Vsat.low-saturation-voltage capability of bipolar transistors as illustrated in Figure 1, and they are the right choice for high-current and high voltage applications. IGBT and MOSFET operation is very similar. A positive voltage, applied from the emitter to gate terminals, produces a flow of electrons toward the gate terminal in the body region. If Oct 23, 2013 · The saturation voltage is a peculiar spec which is not needed by MOSFETs. Bipolar junction transistors have worked for decades to get a Vsat down to 0.1 volt, but for a MOSFET it is 0.00000 volts. The npn has a base p material swamped with electrons from collector to emitter, shorting out any diode drop artifacts. 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 the maximum linear hFE current gain into this non-linear mode, as the collector is no longer a high resistance current source but with …
