Sfc2723 datasheet 2n3904

2002. 9. 12 1/4 semiconductor technical data 2n3904 epitaxial planar npn transistor revision no : 1 general purpose application. switching application.

At 20mA, that's about 120 Ohms. The current gain depends on the collector current, but figure on 50. With a base current of 20mA, that's a collector current of way more than the 2N3904 can handle, so 20mA will saturate it thoroughly. You can probably get by with a lower base current. Look at a 2N3904 datasheet for gain at different collector ...

Most likely the current gain is less, and and maybe also the maximal voltages. Depending on your application that may be OK, which is quite likely if it is not too demanding. The correct thing would for you to check the numbers in the data sheet. 2n3904 [Old version datasheet] Medium Integrated Power Solution Using a Dual DC/DC Converter and an LDO [Old version datasheet] High-Integration, High-Efficiency Power Solution Using DC/DC Converters With DVFS
