ABSTRACT:
A bidirectional power FET circuit for AC application has a plurality of pairs of enhancement mode power FETs. Each pair has first and second power FETs connected drain to drain in series relation. The pairs are stacked in series between first and second main terminals. A plurality of gating circuits, one gating circuit for each power FET pair, are stacked in series for driving the power FET pairs sequentially into conduction from a single gate terminal.
