High hfe transistor
Web5 de nov. de 2008 · hfe is AC current gain. The 2N3904 transistor has an hFE from 100 to 300 when its current is 10mA and its VCE is 1V. It is typically 230 on the graph. Its hfe is … WebAt this point I have to calculate resistance for the base of transistor. In tutorial its as following hfe = Ic / Ib Ib = Ic / hfe Ib = 0.03 A / 75 Ib = 0.0004 A => 0.4 mA R1 = U / Ib R1 = 5V / 0.0004 A R1 = 12500 Ohm 2N3904 datasheet states the H (fe) is 30-300 when lc = 100mA (mine is 130mA) and Vce = 1V.
