WARP Speed IGBT - International Rectifier

IGBTs are voltage-controlled power transistors, that have higher current densities than equivalent high-voltage power MOSFETs.

WARP Speed IGBT - International Rectifier

Features Include
  • 2 to 2.5 times the current density of MOSFETs
  • Lower conduction losses at equivalent current rating compared to MOSFETs
  • Reduced current tail for high frequency operation
  • "Positive-only" gate drive
IRG4PC40W - 600V Warp 60-150 kHz Discrete IGBT in a TO-247AC package

Lower switching losses allow more cost-effective operation than power MOSFETs up to 150 kHz ("hard switched" mode)  

Of particular benefit to single-ended converters and boost PFC topologies 150W and higher 

Low conduction losses and minimal minority-carrier recombination make these an excellent option for resonant mode switching as well (up to >>300 kHz)
