ABSTRACT:
A power transistor (11) having a control electrode (16), a first electrode (17), a second electrode (181), and a kelvin electrode (19) is provided. The power transistor (11) comprises a plurality of transistors (12-15) coupled in parallel. Each transistor having a control electrode, a first electrode, and a second electrode coupled respectively to the control electrode (16) , first electrode (17) , and second electrode (18) of the power transistor (11). A plurality of first resistors (26-29) reduce oscillation and ringing, each first resistor is coupled between the kelvin electrode (19) and a second electrode of a transistor of the plurality of transistors (12-15). A plurality of second resistors (21-24) also reduces oscillation and ringing, each second resistor is coupled between the control electrode (16) and a control electrode of a transistor of the plurality of transistors (12-15).
