Q & A

PN2222A NPN Transistors is for use as a medium power amplifier and switch requiring collector currents up to 500mA

What are PNP and NPN transistors?

NPN and PNP refer to the arrangement of the pieces that make up the transistor. The practical result is the direction of the current flow. … An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). In a PNP transistor, the type of the layers is reversed.

What does an NPN transistor do?

The emitter “emits” electrons into the base, which controls the number of electrons the emitter emits

What are the basic types of transistors?

There are two types of standard (bipolar junction) transistors, NPN and PNP, with different circuit symbols as shown. …

The leads are labelled base (B), collector (C) and emitter (E).
