The circuit symbol of silicon carbide MOSFET is similar to that of traditional silicon MOSFET, except that some special marks are added to the symbol to indicate its characteristics.
The following are common circuit symbols for silicon carbide MOSFETs:
Among them, D, G, and S respectively represent the drain, gate, and source of the transistor, and N represents that the transistor is an N-channel MOSFET. Unlike traditional silicon MOSFETs, a small arrow is usually added between the gate and source in the symbol to indicate the channel direction of the silicon carbide MOSFET. In addition, some symbols also add a diagonal line between the source and drain to indicate that the transistor is bipolar.
It should be noted that there is no unified standard for the symbols of silicon carbide MOSFETs, and different manufacturers and applications may use different symbols. Therefore, in specific applications, it is necessary to choose appropriate symbols based on the actual situation.
