The first external electrode, the drain electrode and the source electrode of the MOSFET chip, and the second external electrode are disposed to be overlapped in a direction of the center axis. The drain electrode of the MOSFET chip and the first external electrode are connected. The source electrode of the MOSFET chip and the second external electrode are connected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device, and alternator and power converter using the semiconductor device","description":"Provided is a semiconductor device including: a first external electrode which includes a circular outer peripheral portion; a MOSFET chip; a control circuit chip which receives voltages of a drain el","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9831145","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
