How To remember the direction of PNP and NPN Transistor. One of the Easiest way. 

 FINDING THE BASE  and determining NPN or PNP

Get an unknown transistor and test it with a multimeter set to "x10"
Try the 6 combinations and when you have the black probe on a pin and the red probe touches
 the other pins
 and the meter swings nearly full scale, you have an NPN transistor.
 The black probe is BASE
If the red probe touches a pin and the black probe produces a swing on the other two pins, you have a PNP transistor.
 The red probe is BASE
If the needle swings FULL SCALE or if it swings for more than 2 readings, the transistor is FAULTY.
