Application Scenarios & Design Considerations

Discrete, IGBT

Alternative Part Number

  • IRGS4065DTRRPBF --: N-channel IGBT in TO-252/D-PAK with comparable 600V-class rating and low saturation voltage, suitable for switching applications similar to the SGR20N40LTF.
  • FGD20N40 --: N-channel IGBT rated around 400V/20A in D-PAK, closely matching the voltage and current class of the original device.
  • STGD20N40L --: 400V/20A N-channel IGBT in D-PAK with integrated freewheeling diode, a direct functional substitute for the SGR20N40LTF.
  • IRG4BC20UD --: Similar 600V-class ultrafast IGBT in TO-220, widely available and electrically comparable for switching applications.
  • FGA25N120ANTD --: Higher voltage NPT IGBT with integrated fast diode, suitable drop-in for rugged switching where extra margin is acceptable.
  • STGP10NC60KD --: 600V fast IGBT in TO-220 with co-packaged diode, good functional substitute when lower current rating is acceptable.
