Hello, readers, welcome to the new post. In this post we will read the Introduction to the 2N3906 PNP Transistor. A transistor is a device used for different switching and development applications. It has 2 main categories the first one is NPN and the second is PNP. The PNP transistor is so structured that there are three layers on both ends with a P-type device and the center of the N semiconductor is suspended.
There are three main terminals with the first one the emitter the second the collector and the third the base. Here we combine the various parameters about these components and learn how to apply them to different projects so let’s get started.
Introduction to 2N3906 PNP Transistor
- The 2N3906 has PNP configured BJT transistor and is very commonly used in circuits where the need of amplifiers and switches.
- Normally preferred for circuits where less value current i needed and less volts has the ability to work at high speed.
- It comes in packaging of T0-92 and three main pinouts emitter-base and collector
- The value of collector current given to it is two hundred milliamperes with the value of VCE is forty volts
- It was designed by the famous electronic company Motorola
- Its configuration is like to the BC557 transistor and used for the high value of current applications due to the large value of VCE.
- Its gain is less than other amplifiers normally has three hundred so not prefer for large amplifier circuits
- In switching applications it prefers since can handle the value of current up to 0.2 ampers.
2N3906 PNP Transistor Pinout
- There are three main pinouts it has’
- EMitter: Current comes out from this point
- Base: Work as a control for components like tap
- Collector Larger than other two parts and get the supply

2N3906 Working in the PNP Circuit
- Here we have made a PNP transistor-configured circuit where 2N3906 works as a switch or amplifier.
- The plus 3V connected with the emitter pin of the transistor. Normally open push button configured with base of transistor. When it presses, there is no current flow in the base of the transistor.
- So it is in the ON state when not pressed. So the LED connected with the collector of PNP is on.
- If the push button is clicked and the transistor is off and the LED is off. It is due to that base voltage being higher as compared to emitter voltage that stops current flow.
How to increase the working life of 2N3906
- For longer working life of transistor, it is good to not operate with a load more than 200 mA. Do not use a load over 40V DC and connect in a circuit with a base resistor and confirm the pin arrangement before putting the circuit on the right.
- The working range temperature is -55 centigrade and above +150 centigrade.
