A semiconductor arrangement comprising; a normally-on transistor having first and second main terminals and a control terminal, a normally-off transistor having first and second main terminals and a control terminal, the transistors connected in a cascode arrangement by a connection between one of the main terminals of the normally-on transistor and one of the main terminals of the normally-off transistor, a current-source arrangement connected to a node on the connection and configured to provide for control of the voltage at said node between the normally-on and normally-off transistors by providing for a predetermined current flow, wherein the semiconductor arrangement comprises a first semiconductor die of III-V semiconductor type having the normally-on transistor formed therein and a second semiconductor die having the normally-off transistor formed therein, the current-source arrangement formed in the first and/or second semiconductor dies.
