2N2222 Datasheet. Specs and Replacement
The 2N2222 is one of the most widely used NPN bipolar junction transistors, valued for its robustness, versatility, and low cost. Designed primarily for low-power switching and amplification, it supports a typical collector current up to 800mA and operates efficiently in the DC to low-MHz range, making it suitable for audio circuits, RF stages, digital control interfaces. When a small base current is applied, the device allows a much larger current to flow from collector to emitter, enabling signal amplification with a current gain typically between 100 and 300. The 2N2222 also features a relatively high collector-emitter voltage rating (Vceo = 30V) and fast switching times, which contribute to its reliability in pulse-driven applications. Its TO18 or plastic TO92 packaging ensures easy integration into both prototyping and production designs.
