WebThe 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, ... The 2N3904 exhibits its forward gain (beta) peak at a lower current than the 2N2222, and is useful in amplifier applications with reduced I c, e.g., ... WebBeta (β) is a characteristic of each transistor. This feature is found in the NTE, ECG manuals, etc. These manuals have a minimum or approximate values of the real values. This means that we do not know the real beta of a specific transistor. Keep in mind that two transistors with the same name (e.g. 2N2222) may have different betas.
WebMay 17, 2011 · 3,068. I think you are mixing BJT gain beta with FET transconductance gm. Beta is the ratio of collecter current to base current i.e input is base current Ib and output is collector current Ic. Transconductance is the ratio of drain current to gate voltage i.e input is gate to source voltage Vgs and output is drain current Id. May 15, 2011.
