IGBTs for driving PDPs that respond to the high-speed switching characteristics and low loss characteristics demands that accompany reduced power consumption and higher video quality. We have achieved the ideal IGBTs for driving PDPs by taking full advantage of the IGBT characteristic of low power loss in the high current region compared to power MOSFETs.

Points on Appeal (Features)

1. Can control high currents.
2. Heat generation during circuit operation is minimized through high-speed switching and low VCE(sat) characteristics
