The 2N2907, also known as the PN2907, is a small PNP BJT transistor used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds.
It is a 1-amp, 50 volt, 300 milli-watt transistor capable of operating up to 100 Megahertz, with a Beta of at least 100. It's used in a variety of analog amplification and switching applications.
It is available in a variety of small through-hole and surface mount packages including TO-92, SOT-23, and SOT-223.
