On Semiconductors

Silicon carbide (SiC) semiconductors have become an indispensable part of electric vehicle (EV) power circuits due to their wide band gap, stable lattice structure and excellent thermal conductivity compared to silicon technology. Furthermore, unlike silicon which degrades with radiation exposure over time, SiC remains suitable for space and nuclear applications – driving up demand even further for SiC chips.

Silicon Carbide (SiC) is a versatile material capable of withstanding high temperatures, voltages and frequencies – characteristics which make it suitable for power electronic devices such as converters, inverters, power supplies and battery chargers. SiC chips are projected to reach $13.9 billion worldwide by 2027 with power electronics holding the highest market share due to an increasing need for electric vehicles requiring more powerful chips.

Microchip is an industry-leading supplier of silicon carbide products. Their vast array of discrete and module products can be found across automotive, industrial, transportation and telecommunication applications – such as automobiles, industrial machinery and telecom.
