Can you convert the BJT as a switch?

The transistor can be used as a switch if biased in the saturation and cut-off regions. This allows current to flow (or not) in other parts of a circuit. Because a transistor’s collector current is proportionally limited by its base current, it can be used as a sort of current-controlled switch.

In which region transistor works as a switch?

saturation region
Transistor acts as a switch in the saturation region and cutoff region. The emitter-base junction and the collector-base junction is reverse biased in the cutoff region. Both the junctions are forward biased in the saturation region.

Can a transistor be used as a solid state switch?

However, both the NPN & PNP type bipolar transistors can be made to operate as “ON/OFF” type solid state switch by biasing the transistors Base terminal differently to that for a signal amplifier. Solid state switches are one of the main applications for the use of transistor to switch a DC output “ON” or “OFF”.

How is a bipolar transistor used as a switch?

If the circuit uses the Bipolar Transistor as a switch, then the transistor’s biasing, whether NPN or PNP, is designed to operate the transistor on both sides of the previously seen “I-V” characteristic curves. The transistor switch operating areas are referred to as the Saturation Region and the Cut-off Area.

What are the areas of operation of a transistor switch?

The areas of operation for a transistor switch are known as the Saturation Region and the Cut-off Region.

When did William Shockley invent the transistor?

The transistor is a 3 pin semiconductor module used for different amplifier and switching circuits. It was created by William Shockley (who was a physicist of United States of America) in 1947. It also used in different engineering projects and circuitry.
