Semiconductor apparatus, ignition device for internal combustion engine, and internal combustion engine system

An ignition device for an internal combustion engine comprising a semiconductor apparatus including:

• a semiconductor device having a high-voltage terminal and a low-voltage terminal;
• a high-voltage electrode having an end connected to the high-voltage terminal;
• a low-voltage electrode having an end connected to the low-voltage terminal;
• a resin sealing the semiconductor device, the end of the high-voltage electrode, and the end of the low-voltage electrode;
• an insulating substrate;
• a first wire directly connecting the low-voltage electrode to the semiconductor device, and a second wire directly connecting the low-voltage electrode to the insulating substrate;
• a first discharge electrode provided to a portion of the high-voltage electrode not covered by the resin;
• and
• a second discharge electrode provided to a portion of the low-voltage electrode not covered by the resin,
• wherein the first and second discharge electrodes protrude to face each other.
