To start using VCE Designer, you need to make sure you have chosen the VCE Exam Simulator PRO as your Avanset software option (VCE Designer is only included in the PRO package):

Transistor Vce Saturation voltage Forum for Electronic Vce(sat) is usually something like 0.2V, and it's usually safe to use 0V as a first approximation Vce(sat) is usually something like 0.2V, and it's usually safe to use 0V as a first approximation. First, assume the transistor is saturated, and therefore Vce = Vce(sat). In figure denoted as (c) VBB is increasing to give a base current of 400uA and collector current of forty milliamperes. The Q point for this state is shone on graph as Q2. Since VCE(sat) is very small compared to VCC, it can usually be neglected The formula for collector saturation current is. Conditions in Saturation : As you have learned, when the base-emitter junction is forward-biased and there is enough base current to produce a maximum collector current, the transistor is saturated. als (V CE (sat)) has reached its lowest saturation voltage of.1V. The graph indicates the Vce = 0.06V for saturation saturation voltage, collector-emitter (VCE(sat)) JEDE The table in the data sheet says the max Vce for saturation is 0.2V. I am confused as to what value to expect for Vce when saturation occurs. According to the table in the data sheet, as long as Vce is under 0.2V the transistor should be saturated. vi VCC VsCE (at Switching to a 1K resistor, gives Vce of 0.061v. vi IC =0 V0 =VCC By contrast if the voltage is high, say equal to, the transistor is driven into saturation and the output is equal to which is low. But, we do know th This bias reference voltage can be easily calculated using the simple voltage divider formula below: Transistor Bias Voltage The same supply voltage, ( Vcc ) also determines the maximum Collector current, Ic when the transistor is switched fully ON (saturation), Vce = 0 If the voltage is zero (low) the transistor is in the cutoff region, the current and the voltage (high). Thus, we ENFORCE the conditions: V CE = 0.2 V V BE = 0.7 V V CB = -0.5 V Now lets ANALYZE the circuit ! 10.0 K 2.0 K 5.7 V 10 K 10.7 V + 0.2 - + 0.7 - + -0.5 - i B i E i C Note that we cannot directly determine the currents, as we do not know the base voltage, emitter voltage, or collector voltage. Lets ASSUME instead that the BJT is in saturation. If you don't know it, and you have no other information about the specific transistor, you can only measure it. Its the voltage across C and E when the given (maximum, saturation) current is flowing through C an E (and Vbe sat. Saturation Vce is a value in the datasheet of a transistor, and it does not change. IEC 747‑7.) NOTE This is the voltage between the collector and emitter.Įlectronic - BJT: Equation of Vce for Saturation Region als under conditions of base current or base-emitter voltage beyond which the collector current remains essentially constant as the base current or voltage is increased. Diodes Inc (nee Zetex) has many of the earliest process patents of ultra-low Vce(sat) at high currents. You must refer to the Vce(sat) parametric model or datasheet for this property. The chip size, doping, layered etching methods all are factors. There is no formula for Vce(sat) because this bulk resistance is process dependent.
