Abstract
Object: The present invention is intended to supply an internal combustion engine-use igniter that is compact, excellent in mountability, and can contribute to the simplification and automation of assembly and to cost reduction. Implementing means: An insulated gate bipolar transistor (IGBT) is used as the ignition coil switching device for the internal combustion engine. The IGBT and a current limiting circuit intended to protect it from an overcurrent are formed on single semiconductor chip , and this semiconductor chip and radio noise reduction capacitor are contained in single packaging unit having external input and output terminals to . Packaging unit is transfer-molded using a material such as epoxy resin.
