  • Introduction of features of the TO-247-4L package, a 4 leads structure, which has a source terminal for gate drive circuit additionally compared with the conventional 3 leads pacckage.
  • Describing the 4 leads package feature that achievs less oscillation of gate signal and lower switching loss than the 3 leads because the 4 leads package is not affected by parasitic inductance of source wiring
