IRGPC40U Description

Insulated  Gate  Bipolar  Transistors  (IGBTs)  from  International  Rectifier have higher usable current densities than comparable bipolar transistors,  while at the same time having simpler gate-drive requirements than the familiar power MOSFET.  They provide substantial benefits to a host of high-voltage, high-current applications.

IRGPC40U Benefits

The switching-loss rating  includes  all  "tail"  losses

Optimized for high operating frequency (over 5kHz)
