【Abstract】 The high\|power transistor always is a low\|voltage and high\|current apparatus. Radiation is very important for it. Based on the normal radiation theory, this paper discussed the heat\|transmission process of high\|power D\|MOS field effect transistor (FET) BLF147, and schemed out its radiated passageway and over\|heated protection circuits.更多还原
