2N2219 NPN Transistor

The 2N2219 is a small-signal NPN bipolar junction transistor (BJT) manufactured using the epitaxial planar process. Encased in a robust TO-39 metal package, this transistor is designed for general-purpose amplification and switching tasks. It features a continuous collector current of 800mA and a collector-emitter voltage of 30V, making it suitable for low to medium power applications. With a typical current gain (hFE) of 50, it ensures reliable signal amplification. The 2N2219 is widely used in audio amplifiers, signal processing circuits, and switching applications due to its fast switching speed and thermal stability. Its metal can package provides excellent durability and heat dissipation compared to plastic alternatives. Choose the 2N2219 for your hobbyist projects, educational electronics, or professional circuit designs where reliability and performance are key. It is a direct equivalent to the 2N2219A variant and is readily available in the Indian market.
