PNP
The PNP type consists of two P-Regions separated by N-Region, so we can suppose
a diode between B - C and between B - E.
Now, we can test the PNP transistor as 2 diodes. To test the first diode (B - E), we
need to connect the black probe to the cathode which is the base of the transistor and
connect the red probe to the anode which is the emitter of the transistor.
