Turn-on Sequence: Apply Vg1 = -2.5V, Vg2 = -2.5V, followed by Vd1 = Vd2 = 7V, lastly increase Vg1 & Vg2 in sequence until required Id1 and Id2 is obtained. b. Turn-off Sequence: Turn off Vd1 & Vd2, followed by Vg1 & Vg2 3) Demonstration board available upon request. Specifications are subject to change without notice.
