MOTOROLA 2N2219 NPN bipolar junction transistor (NOS)

The 2N2219 is a robust NPN bipolar junction transistor designed for general-purpose amplification and switching applications. Encased in a hermetic TO-39 metal can, it offers improved heat dissipation and reliable performance under higher power loads. Key specifications include a collector-emitter voltage of 30 V (40 V for the 2N2219A), collector-base voltage up to 60 V (75 V for 2N2219A), continuous collector current capacity of 800 mA, and power dissipation rated at 800 mW. Its high transition frequency—250 MHz (300 MHz for 2N2219A)—makes it suitable for small-signal operations requiring fast switching and stable gain.
