What is BSS123? Vertical D-MOS Transistor

What is BSS123?

An N-channel enhancement mode vertical D-MOS transistor is a type of field-effect transistor (FET) that is designed for high-power applications. It uses a vertical structure to improve its performance.

In a vertical D-MOS transistor, the source and drain regions are located on opposite sides of the silicon substrate, with the gate electrode running vertically between them. When a voltage is applied to the gate, an electric field is created that controls the flow of current through the channel.

The “D” in D-MOS stands for “double-diffused”, which refers to the way that the doping profiles are created during the manufacturing process. This allows for a more precise control of the channel and reduces the on-resistance of the device, making it more efficient.

The “MOS” in MOS transistor stands for “metal-oxide-semiconductor”, which refers to the way that the gate electrode is insulated from the channel by a thin oxide layer.
