Compare to conventional mica or silicon pad materials, the ceramic insulators material is more beneficial for MOSFETs mounting such as improve the performance of high frequency because of their high thermal conductivity and high electrical resistance. The ceramic insulators mostly choose the 96% alumina and aluminum nitride ceramics material.
TO-220 Ceramic Insulator Cooling Pads also called as Ceramic Heat Spreader, it is resistant to high temperature and pressure. The surface of the ceramic insulator sheet is smooth, without burrs and burrs. It can Heat evenly, rapid heat dissipation, it is not easy to break, acid and alkali corrosion resistance, durable and so on advantages. Below is the drawing of TO-220 and other customzied TO package ceramic insulators we can make.
