When a transistor is in saturation VcE is approximately equal to?
0.7V When a transistor switch is in saturation, VcE is approximately equal to c. 0.2V a.
What is the difference between hard saturation region and quasi saturation region wrt a power transistor?
A transistor is said to be in the quasi saturation stage if base-emitter and collector-base are connected in forwarding bias. A transistor is said to be in hard saturation if base-emitter and collector-base are connected in forwarding bias.
When a transistor is used as a switch it is stable in which two distinct regions?
When a transistor is used as a switch, it is stable in which two distinct regions? Class B operation is provided when the dc bias leaves the transistor biased just off, the transistor turning on when the ac signal is applied. A silicon power transistor is operated with a heat sink (θSA = 1.5ºC/W).
Which of the following is true for a pnp transistor in a saturation region?
10. Which of the following is true for a pnp transistor in saturation region? Explanation: Whether the transistor in npn or pnp, for it be in saturation region the EB junction must be forward bias the CB junction must be forward bias.
Which of the following is true for a NPN transistor in the saturation region *?
6. Which of the following is true for a npn transistor in the saturation region? Explanation: The commonly used npn transistors have a potential difference of around 0.5V between he collector and the base. Explanation: The value of Vcb is -0.5V for a pnp transistor and 0.5V for an npn transistor.
When a bipolar junction transistor is used as a switch in which two distinct modes does it operate?
The transistor acts as a switch in the cut-off mode and the saturation mode. The transistor is fully off in the cutoff region and fully on the saturation region.
What is the difference between saturation and current in a transistor?
In the active region (some collector current, more than a few tenths of a volt above the emitter), useful for amplifier applications In saturation (collector a few tenths of a volt above emitter), large current useful for “switch on” applications. Transistor load line
Can a transistor work in beta mode in saturation mode?
No. Transistor will work in different beta in saturation mode and that beta is called as beta forced . When there is sufficiently large base voltage the transistor will be driven into the saturation And collector to emitter voltage is small.
What is the value of VCE in saturation region of transistor?
When transistor is in saturation the collector current will be determined by (Vcc-Vce (sat))/Rc .From this we can say that Ic increases very slightly in the saturation region.The value of Vce range from 0.1 to 0.3 V.
Why is beta force always less than beta force in transistor?
The beta force will be always less than the beta because as Ib increases ,Ic almost constant the Ie will increase with Ib so the current gain in saturation region will be always lesser than that of active region. , Electronics and communications major. In a transistor, both emitter and collector regions are of the same nature of doping.
