PNP complementary types are 2N3905 and 2N3906. Web2N3904 devices are silicon NPN transistors designed for general purpose amplifier and switching applications. The hFE of the 2N3904 varies between 30 to 300 (depending on the test conditions), and the current gain. In the sheet above, it is also known as as hFE. When figuring out DC current gain, the beta value is part of the formula.

Per and Lancelot: A 2N3904 transistor’s beta max value is 150 and min value is 100.
