The variable gate FET includes a FET and a gate control device that is attached to a surface or a heat-generating portion of the FET and is connected to a gate terminal of the FET so as to vary a voltage of the gate terminal. A channel current between the source and drain is controlled by the gate control device that varies the voltage of the gate terminal when the temperature of the FET increases above a predetermined temperature."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable gate field-effect transistor and electrical and electronic apparatus including the same","description":"Provided are a variable field effect transistor (FET) designed to suppress a reduction of current between a source and a drain due to heat while decreasing a temperature of the FET, and an electrical ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8502478","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.
