What is VBE on in saturation mode?

In saturation mode both of the “diodes” in the transistor are forward biased. That means VBE must be greater than 0,and so must VBC. Because the junction from base to emitter looks just like a diode, in reality, VBE must be greater than a threshold voltage to enter saturation.

Is VBE 0.7 in saturation?

In saturation region for npn BJT made of silicon, Vbe is 0.8 volt not 0.7 volt.

What is the value of VBE in cutoff mode of a silicon NPN transistor?

In an npn transistor base is positive(p) and emitter is negative(n). So the potential barrier vbe=0.7V.

What is VBE in PNP?

The voltage between the Base and Emitter ( VBE ), is now negative at the Base and positive at the Emitter because for a PNP transistor, the Base terminal is always biased negative with respect to the Emitter.

What does VBE stand for?

VBE

Acronym	Definition
VBE	Visual Basic Environment
VBE	Video Bios Extension
VBE	Visual Basic Script Encoded
VBE	Visual Basic Editor

What is VBE in PNP transistor?

Then the base voltage, ( Vbe ) of a NPN transistor must be greater than this 0.7V otherwise the transistor will not conduct with the base current given as. Where: Ib is the base current, Vb is the base bias voltage, Vbe is the base-emitter volt drop (0.7v) and Rb is the base input resistor.

What does VCEQ mean?

The Q-point is on the DC load line and represents the current flowing in output circuit and voltage across it. In our case, they are IC and VCE. The value of current and voltage at Q-point are written as (VCEQ, ICQ).

Is VBE constant?

In active region, VBE is constant by definition and should be extremely close to 0.7V for silicon devices.

What is base emitter voltage?

saturation voltage, base-emitter (VBE(sat)) The voltage between the base and emitter terminals for specified base-current and collector-current conditions that are intended to ensure that the collector junction is forward-biased.

What you mean by vibes?

: a distinctive feeling or quality capable of being sensed This place has a good/bad vibe. She gave me a weird vibe. =

What is the value of VBE in an NPN transistor?

VBE in the NPN transistor is the base emitter voltage and it should be greater than 0.7 i.e positive, to conduct transistor blow this transistor don’t turn on.

What is saturation mode of NPN BJT?

The NPN BJT will enter the saturation mode when Vcb will below some value. Sedra&Smith use value of 0.4V, but this will be device dependent. Though I have no idea why you would whant to use BJT as a switch.

What is the V be of a bipolar junction transistor?

V BE is the voltage that falls between the base and emitter of a bipolar junction transistor. V BE is approximately 0.7V for a silicon transistor. For a germanium transistor (which is more rare), V BE is approximately 0.3V.

What is the saturation mode of a a transistor?

A transistor in saturation mode acts like a short circuit between collector and emitter. In saturation mode both of the “diodes” in the transistor are forward biased. That means V BE must be greater than 0,
