Basic igbt subcircuitIntroductionYou ve finally tested a version of your design that seemsto work well, but you would feel a lot better if you KNEWthe circuit would work well with all the devices that thevendor will supply in production. You found a MODEL ina library, but you are not sure what specifications from thedata book apply to that MODEL . The following paragraphswill try to clarify the relationship between data bookspecifications and a new Insulated Gate Bipolar Transistor( igbt ) subcircuit SPICE An IGBTAn igbt is really just a power MOSFET with an addedjunction in series with the drain. This creates a parasitictransistor driven by the MOSFET and permits increasedcurrent flow in the same die area.
