An electronic circuit and a method for controlling a power field effect transistor. The electronic circuit includes a power field effect transistor having a semiconductor body, which has a drain zone, a drift zone, a source zone and a bulk zone. The power field effect transistor further includes a gate and a field plate. The field plate is placed adjacent to the drift zone and is isolated from the drift zone. A switch circuitry is provided for electrically connecting the field plate depending on the drain-source voltage such that the field plate is electrically connected to the drain zone, if |UDS|>UT, where UT is a predetermined voltage, and if |UDS|>UT, the field plate is connected to an electrode having an electrode-source voltage UES.
