Technical Introduction
Power semiconductor low-voltage Trench MOSFETs have evolved from the earlier planar gate field-effect transistors (FETs). These devices improve the horizontal conductive channel by switching to a vertical conductive channel, making it possible to further reduce the unit cell area. At the same time, a low-doped epitaxial layer is used to provide sufficient voltage tolerance, and by varying the doping concentration and thickness of the epitaxial layer, devices with different voltage ratings can be easily obtained. While ensuring that the device's breakdown voltage meets requirements, an important development trend for trench power devices is to make the size of individual unit cells smaller and the unit cell density higher, thereby helping to reduce the on-resistance per unit area.
The medium and low-voltage trench (Trench) MOSFET series products cover voltage ranges from N/P20V - 100V. Different design schemes are used to meet the specific performance requirements of various application fields, ensuring excellent performance in each respective application.
