Brief PNP BJT emitter follower common collector – 2N3906 bipolar junction transistor

Table of Contents

Setting a voltage with a PNP bipolar junction transistor (BJT) is a bit more awkward than with a NPN BJT. But, it can just as easily be done once you take into account that you will be working with opposite power polarities as far as the transistor is concerned.

Voltage across the emitter resistor sets the current through it and series components (transistor and load) as long as enough voltage is used.

Voltage across the emitter resistor is the voltage at the base with an approx.  0.6V difference (0.6V higher than ground).

I love my kindle fire! I can read books and watch movies anywhere I go.



The ad above is to a best selling multimeter since the ones I use are unfortunately not being sold anymore. It still helps this site if you click the link, check out the meter and compare it with other meters to see what looks best for you!



Updated version of one of my favorite multimeters. It has some oscilloscope capabilities.
