Motorola 2N2219 NPN silicon planar epitaxial transistor (silver leads)

The 2N2219 is an NPN silicon planar epitaxial transistor tailored for small-signal amplification and switching. Housed in a TO-39 metal can, it offers superior heat dissipation, enabling power handling up to 3W at 25°C case temperature. It supports a maximum collector-emitter voltage of 30V and collector current up to 800mA, making it suitable for robust general-purpose applications where reliability and thermal performance are critical.
