Web1. On Semiconductor published a guide on how to interpret their IGBT datasheets. It says that: The pulsed collector current describes the peak collector current pulse above the … Web8 Jun 2024 · When the metal oxide semiconductor field effect transistor (MOSFET) or the insulated gate bipolar transistor (IGBT) is used as the main switching device, the lossless switching could be completed, and the capacitive turn-on loss caused by the internal junction capacitance of MOSFET and the turn-off loss caused by the tail current of IGBT …
WebOne of the hallmarks of voltage-dependent channels is a 'tail current' - deactivation as observed after prior and sufficient activation predominantly at more depolarized … 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.
