Webb14 apr. 2016 · Most of the J113 have V_gs0 around 1.3~1.8 V, with 1.5 V being typical. The beta (I_dss/V_gs0^2) is indeed fairly constant at about 9~10m, which implies that as the pinch off voltage increases, the saturation voltage increases to match. In fact I_dss values nearly all fall on a straight line plotted against V_gs0.
