A dual channel JFET which can be integrated in an IC without adding process steps is disclosed. Pinch-off voltage is determined by lateral width of a first, vertical, channel near the source contact. Maximum drain voltage is determined by drain to gate separation and length of a second, horizontal, channel under the gate. Pinch-off voltage and maximum drain potential are dependent on lateral dimensions of the drain and gate wells and may be independently optimized. A method of fabricating the dual channel JFET is also disclosed.
