2N2905A PNP silicon bipolar transistor

The 2N2905A is a PNP silicon bipolar transistor optimized for high-speed switching and versatile general-purpose use. Housed in a TO-39 metal case, it offers enhanced heat dissipation for reliable operation. Key attributes include a collector-emitter voltage rating of -60 V, continuous collector current of up to -600 mA, and power dissipation ranging from 800 mW (ambient) to 3.0 W (case). With a transition frequency of 200 MHz and a DC current gain between 100 and 300, it performs efficiently across a wide temperature range from -65°C to +200°C. The three leads provide standard emitter, base, and collector connections in the TO-39 configuration.
