A MOSFET has how many terminals?

[A]. 2 or 3
[B]. 3

Answer: Option D

Explanation:

No answer description available for this question.

GATE, SOURCE, DRAIN AND SUBSTRATE, In some cases the substrate internally connected to the source.

Anand Bharti said: (Sep 15, 2012)  
MOSFET has only 3 terminal namely source, drain &gate.please answer me name of 4th terminal.

Amarendra said: (May 5, 2013)  
4th terminal namely called substrate(SS).

Sindhu said: (Aug 31, 2013)  
Substrate is of either p type or n type like source & drain know, I think we are not taken into account the substrate.

Rahul Jain said: (Sep 18, 2013)  
Substrate is not terminal it is material (sio2) etc. So answer is only 3 terminal.

Hegde said: (Feb 22, 2014)  
Externally only 3 terminal are available.

Abu Sayeed said: (Nov 24, 2014)  
If Vsb(source to body voltage) = 0. Then 3 terminal.

If Vsb(source to body voltage) ≠ 0. Then 4 terminal.

It has 3 terminals like JFET. The substrate is the extra one.

Yuvaraj said: (Feb 17, 2016)  
4 terminals that are drain, source, gate, and substrate.

Kamlesh said: (Jun 7, 2016)  
A MOSFET has three terminals.

1. Gate
2. Drain
3. Source.

Sandy said: (Jul 3, 2016)  
I think, MOSFET - 4 terminals.

Jamir said: (Jul 24, 2016)  
MOSFET has 3 terminal only.

Ananya Sharma said: (Aug 10, 2016)  
MOSFET HAS 3 TERMINAL.

* SOURCE
* DRAIN
* GATE

Amresh said: (Feb 23, 2017)  
Can Substrate be a terminal?

Mohan said: (Mar 17, 2017)  
4th terminal is base.

Abdullah said: (Aug 17, 2017)  
I Think answer 3 or 4 is right beacuse in option this is available and we know that in MOSFET substrate is also a terminal otherwise it is internally built in it thats why we say that MOSTET has three terminal.

Ajayvarma said: (Sep 19, 2017)  
Yeah. It may be 3 or 4. According to the design requirements we will take 3 or 4.

4th terminal is substrate terminal.

If Vsb=0 ---3.

If Vsb not equal to zero then 4terminals. That means if sourcr and substrate has different potential then two different terminals will be taken.

3 terminals are conected drain gate source.

Roshan said: (Sep 1, 2018)  
The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistor is a semiconductor device which is widely used for switching and amplifying electronic signals in the electronic devices. The MOSFET is a three terminal device such as source, gate, and drain.

Musiit said: (Dec 27, 2018)  
The terminals are;

- Gate
- Source
- Drain
- Bulk

*Bulk may be present or not depending on the application.

Each MOSFET has 4 terminals called body (B), source (S), gate (G) and drain (D).
