If we consider the gate is positive with respect to the source, then there is a formation of the N-type channel which is close to the gate and it is in the case of the E-MOSFET. ![]() The V-MOSFET is an E-mode FET and there is no exists of the channel in between the drain & source till the gate is positive with respect to the source. The source terminal contacts with the both N+ and P- layers through the SiO2 layer. The N+ layer is the heavily doped layer with a low resistive material and the N- layer is a lightly doped layer with the high resistance region.īoth the horizontal and the V cut surface are covered by the silicon dioxide dielectric layer and the insulated gate metal film is deposited on the SiO2 in the V shape. The V- the shape of power MOSFET is cut to penetrate from the device surface is almost to the N+ substrate to the N+, P, and N – layers. Thus the device is also called as the V-MOSFET or V-FET. The construction of the power MOSFET is in V-configurations, as we can see in the following figure. Working of Power MOSFET and Characteristics They are sufficient in many applications like reducing part count. ![]() Generally, these diodes will have a high forward voltage drop, the current is high. Hence this solution creates a diode between the cathode & anode of the MOSFET and the current blocks in one direction.įor inductive loads, the body diodes utilize the freewheeling diodes in the configuration of H Bridge & half bridge. The connections of the P implantation to the source metallization short the base terminal of the transistor parasitic to its emitter and it prevents the latching.
