Abstract
An ignition apparatus for an internal combustion engine, which is controlled by a control unit, includes a connector, an ignition coil assembly, an igniter and a capacitor. The connector is electrically connected with the control unit, and includes an input terminal, which is electrically connected with the control unit to receive an ignition signal outputted by the control unit. The connector also includes a ground terminal, which is connected with a ground. The igniter includes a switching device that switches a coil current supplied to the ignition coil assembly based on the ignition signal received from the control unit through the connector. The igniter also includes a Zener diode that serves as a protection element of the switching device. The capacitor is provided in parallel with the Zener diode between the input terminal and the ground terminal to form a parallel circuit.
