Usually, the diodes used by most people are made of silicon as the raw material, but the recently popular silicon carbide diodes are those made of silicon carbide as the raw material.

This type of suppressor has the characteristic of "electric pry" and is usually related to 4-layer NPNP silicon controlled bipolar devices or plasma gas/GDT devices.

When conducting, the driving circuit should be able to provide sufficient charging current to quickly raise the voltage between the MOSFET gate and source to the required value, ensuring that the switch tube can be quickly turned on and there is no high-frequency oscillation of the rising edge.
When there is no voltage applied between the gate and source during operation, the PN junction between the drain and source is reversed, so there is no conductive channel. Even if a voltage is applied between the drain and source, the conductive channel is closed and no current flows through.
