PN2222 Overview

The PN2222 is a popular NPN bipolar junction transistor that is used for common low-power intensification or swapping circuits. It is designed for low to intermediate current, modest power, and intermediate voltage, and it may operate at a moderately higher speed.

2N2222 Overview

The 2N2222 is a typical NPN bipolar junction transistor (BJT) used in low-power amplifying or switching applications. It is intended for low to medium current, low power, medium voltage, and relatively fast operation. It was originally created in the TO-18 metal container shown in the image.
