On a transistor data sheet how do you know which min hFe value to use for example for the 2n2222a.
DC Current Gain
(IC = 0.1 mAdc, VCE = 10 Vdc)
(IC = 1.0 mAdc, VCE = 10 Vdc)
(IC = 10 mAdc, VCE = 10 Vdc)
(IC = 10 mAdc, VCE = 10 Vdc, TA = –55°C)
(IC = 150 mAdc, VCE = 10 Vdc)(1)
(IC = 150 mAdc, VCE = 1.0 Vdc)(1)
(IC = 500 mAdc, VCE = 10 Vdc)(1)

If my Ic was going to be 50ma then which hFe value would i use ?
If the voltage supplied to the transistor is less than 10 vdc say 5 vdc insteed that obviously means that vce can not be 10v so how do you choose the hFe from data sheet in this case if the characteristics are based on vce of 10 vdc ?
