Motorola 2N2219A NPN silicon bipolar transistor (silver leads)

The 2N2219A is a robust NPN silicon bipolar transistor optimized for high-speed switching and versatile amplification tasks. Encased in a metal TO-39 package, it offers superior heat dissipation compared to plastic variants. Key parameters include a collector-emitter voltage of 40 V, collector-base voltage of 75 V, and an emitter-base voltage of 6 V. It supports continuous collector currents up to 800 mA and power dissipation from 0.8 W (ambient) to 3.0 W (case). With a transition frequency of 300 MHz and DC current gain between 30 and 100, it is well-suited for demanding electronic designs requiring reliability and performance.
