Minimum RDS of 14 Ω occurs when VGS = -1.0V. As VGS approaches the pinch-off voltage of -6.0V RDS rapidly increases to the maximum value or RDS = 38 Ω. The LS26VNS is specially intended for applications where the drain-source voltage is a low-level AC signal with no DC component. The key device performance is the predictable RDS change from14 to 38 Ω with no change in VGS voltage. The LS26VNS is available in TO-92 (3 Lead), SOT-23 (3 Lead) and small foot-print DFN (8 Lead) packages.
