Abstract
The invention relates to an ignition device for an Otto engine, comprising an ignition coil, a printed circuit board, which carries a control circuit with a power transistor, a plastic housing, in which the ignition coil and the printed circuit board are arranged, and a thermal dissipation element, which protrudes through a wall of the plastic housing. In accordance with this disclosure, the printed circuit board carries a cooling body, which is plugged together with the thermal dissipation element to form a thermal bridge, which dissipates thermal losses of the control circuit out from the plastic housing.
