WebIRG4BC20SDPBF;中文规格书,Datasheet资料. • Generation 4 IGBT's offer highest efficiencies available • IGBT's optimized for specific application conditions • HEXFRED diodes optimized for performance with IGBT's . Minimized recovery characteristics require less/no snubbing • Lower losses than MOSFET's conduction and Diode losses. Webat nominal current is usually still positive but at a much smaller value as compared to a unipolar MOSFET device. The temperature not only influences the static properties but also the dynamic behavior. The increased number of charge carriers, so called plasma, is visible by investigating the tail current during the turn-off of the IGBT.
