【Abstract】 Abstract Based on analysis of the instantaneous current distribution in p base region during the storage period of MCT, an analytical formula is derived in the view point of the charge controlled principle to express its maximum turn off current. The formula relates the maximum turn off current of MCT to the emitter width, length, p base sheet resistance and OFF FET channel resistance. The analysis is verified by a comparison with the results of numerical simulation for the same device.更多还原
