What is the collector to emitter terminal voltage when the transistor is in I saturation region II cut off Region III active region?

As the base current is zero, only small collector leakage current flows. The base emitter junction does not remain in the forward biased because the base current is zero. The collector to emitter voltage is equal to VCC….Cut off, Active & Saturation Region of Transistor.

Region	Base – emitter diode	Emitter – collector diode
Saturation	ON	ON
Active	ON	OFF

What happens in saturation region of transistor?

Saturation region This is the region in which transistor tends to behave as a closed switch. The transistor has the effect of its collector and Emitter being shorted. The collector and Emitter currents are maximum in this mode of operation.

When the transistor is saturation the collector to emitter voltage is?

Explanation: At saturation, the collector-to-emitter voltage is the minimum drop possible occurring due to the non-zero internal resistance of the BJT. Since it cannot decrease further, the current IC cannot increase further. The BJT is said to be saturated.

What is the voltage across the collector to emitter terminal when the transistor is in cutoff region?

Whenever we observe the terminals of a BJT and see that the emitter-base junction is not at least 0.6-0.7 volts, the transistor is in the cutoff region. In cutoff, the transistor appears as an open circuit between the collector and emitter terminals. In the circuit above, this implies Vout is equal to 10 volts.

When the transistor is fully switched off the voltage drop across the transistor VcE is equal to?

Question: When a transistor switch is cut off, Vce is approximately equal to c. 0.2V d. 0.7V When a transistor switch is in saturation, VcE is approximately equal to c. 0.2V a.

What is the difference between cut-off region and saturation region?

If the transistor is cut-off, there is no base current, so there is no collector or emitter current. That is collector emitter pathway is open [See Below Fig.] (ii)]. In saturation, the collector and emitter are, in effect, shorted together.

What does it mean to say that a transistor is saturated?

Saturation is when the transistor is fully turned on. The Beta or hFE is the ratio of Base current flowing from Base to Emitter that is required for the transistor to reach saturation.

What is collector-emitter voltage?

The Collector−Emitter Voltage, VCEO, spec states the maximum voltage that can be applied from the collector to emitter is 50 V. There are two maximum ratings for the input voltage, forward and reverse. The input voltage is defined as the voltage applied from the base and the emitter.

Where is the saturation voltage on a a transistor?

A transistor in saturation would be at the bottom left corner. By “Saturation voltage” they mean the collector to emitter voltage under the given conditions. Usually it is with a forced beta of 10 or 20. In the datasheet segment you show it is with a forced beta of 50.

What is the current of the collector in a transistor?

Collector Current Determination. The base-emitter voltage VBE can be considered to be the controlling variable in determining transistor action. The collector current is related to this voltage by the Ebers-Moll relationship (sometimes labeled the Shockley equation):

What is meant by saturation voltage of the collector?

By “Saturation voltage” they mean the collector to emitter voltage under the given conditions. Usually it is with a forced beta of 10 or 20. In the datasheet segment you show it is with a forced beta of 50.

How does the base-emitter voltage affect the collector current?

An increase in base-emitter voltage VBEby about 60 mV will increase the collector current ICby about a factor of 10. The effective AC series resistance of the emitter is about 25/ICohms. The base-emitter voltage VBEis temperature dependent, decreasing about 2.1 mV/C
