16. A MOSFET, comprising:

  • a semiconductor body having a source region, a drift region and a drain region having a first conductivity type and a body region having a second conductivity type, the body region being between the source region and the drift region;

    a gate electrode disposed adjacent the body region, the gate electrode being isolated by a gate dielectric;

    a source electrode which contacts the source region and the body region; and

    a channel region of the first conductivity type extending from the source electrode to the drift region, so that a pn junction between the body region and the channel region is provided, wherein a doping concentration of the body region and a width of the channel region are such that the intrinsic depletion zone of the channel region cuts off when the MOSFET is in a non-biased state.
