How PNP-transistor works as a switch?
Explanation:
PNP-transistor:
When two p-type materials are doped into one n-type material then the transistor is known as a PNP transistor.
PNP-transistor works as a switch:
The Emitter potential for a PNP transistor needs to be positive with respect to the Base. The transistor then functions as a solid-state "single-pole single-throw" (SPST) switch. The transistor becomes "OFF," operating like an open switch when a zero signal is applied to the base, and no collector current flows.
Draw the required diagram:
PNP transistors operate similarly to NPN transistors in terms of switching, but current flows from the base. Negative ground configurations use this kind of switching.
The base terminal of a PNP transistor is always negatively biased in relation to the emitter.
- The tiny quantity of base current regulated both the emitter and collector currents.
- A PNP transistor's base is where the current enters. It is a constant that the base terminal has a negative bias toward the emitter.
- The current between collector and emitter will conduct when we add a little negative supply at the base of PNP.
