TAJD155K050RNJ_TAJD155K050RNJ Introduction

The direction of the arrow in the symbol indicates from P (substrate) to N (channel). The source and substrate of MOS tubes are usually connected together (most tubes are connected before leaving the factory). Figures (a) and (b) are its schematic structural diagram and representative symbols, respectively. An electrode B is also drawn out on the substrate, which constitutes an N-channel enhancement type MOS transistor. Its grid is insulated from other electrodes.

For the P-type MOS tube, if the voltage of S is higher than that of G (there is a voltage difference between G and S, the specific level depends on the specific MOS tube), the connection between D and S will be conducted (the voltage direction S points to D), this At this time, the gap between D and S is equivalent to a very small resistance. If the gap between G and S is low (the specific level depends on the specific MOS tube), the gap between D and S will be cut off. At this time, the gap between D and S is equivalent to a very small resistor. If the resistance is too large, current cannot flow.

The IGBT is constructed by adding a layer to the drain of the MOSFET. In addition, for IGBTs and MOSFETs with similar power capacity, the speed of IGBTs may be slower than that of MOSFETs, because IGBTs have turn-off tailing time. Due to the long turn-off tailing time of IGBTs, the dead time will also be extended, which will affect the switching frequency. The ideal equivalent circuit of IGBT is shown in the figure below. IGBT is actually a combination of MOSFET and transistor triode. MOSFET has the disadvantage of high on-resistance, but IGBT overcomes this shortcoming, and IGBT still has low on-resistance at high voltage. . Structural features of MOS tube and IGBT The internal structure of MOS tube and IGBT tube is shown in the figure below.
