Abstract
A temperature-indicating field effect transistor (100) includes a transistor die (101) including a drain (103), a source (105), and a gate (107). A temperature measurement device (109, 111) is thermally coupled to the transistor die (101) and electrically coupled to the gate (107). A transistor package (113) encapsulates the transistor die (101) and the temperature measurement device (109, 111). The transistor package (113) has three externally accessible terminals including a first terminal (115) connected to the drain (103), a second terminal (117) connected to the source (105), and an input terminal (119) coupled to the temperature measurement device (109, 111).
