The 2N2907 is a commonly available PNP bipolar junction 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. This transistor was made by several manufacturers; Texas Instruments released a data sheet for their version of this part dated March 1973.[1] An "A" suffix indicates a slightly higher breakdown voltage.[2] These transistors have an enduring popularity with electronics hobbyists.[3]
