Datasheet for the 2SK4066, an N-channel power MOSFET, as indicated by the 2SK prefix of the Japanese semiconductor numbering system. The PDF should list drain-source voltage, continuous current, on-resistance, gate charge, pinout and package drawing. It is useful when a switching transistor in a power supply or motor driver has failed and you need its ratings to choose an equivalent. Compare voltage, current, RDS(on) and package, and measure the gate drive in-circuit before fitting a substitute.
