Silicon Carbide Diodes Market: Introduction
- Silicon carbide diodes are the Schottky diodes which offer high switching performance, efficiency, power density, and low system costs. The diode also provides zero reverse recovery, low forward voltage drop, current stability, high surge voltage capability, and positive temperature coefficient.
- Silicon carbide diodes have various applications such as in photovoltaic solar inverters, electric vehicle chargers, power supplies, and automotive applications. These diodes have low leakage current and high doping as compared to silicon. Also, the direct characterization of silicon changes at high temperature.
- Further, the benefits of silicon carbide diodes includes improved system efficiency, low switching losses, low noise switching, high reliability with high increased power density, and low system cost.
Advantages of silicon carbide diodes over other diodes
- Silicon carbide diodes have low reverse recovery time and lowest forward voltage drop as compared to other diodes. It also has the advantage of low forward losses and negligible switching losses. These features make the diode ideal for power electronics applications.
- Apart from silicon carbide diodes, Gallium arsenide (GaAs) Schottky rectifiers are considered as next generation power components. However, Gallium arsenide has found limited acceptance due to high costs as compared to silicon.
- Another advantage of silicon carbide diode is temperature stability over a wide operating range. This allows parallel connection of multiple devices and also prevents thermal runaway. All these advantages are increasing the adoption of silicon carbide diodes across the globe.
Increasing demand for silicon carbide in electric vehicles creating opportunity
- In electric, hybrid, and fuel cell vehicles, efficiency, size, and cost plays a major role and hence silicon carbide devices are suitable. Silicon carbide also offers temperature stability and operating capability in high temperature which is suitable for electric vehicles.
- Moreover, silicon carbide eliminates the liquid cooling technology from vehicles. Hence, the acceptance of silicon carbide devices in these vehicles is creating high demand for silicon carbide diodes in the market.
High costs associated with silicon carbide diodes
- One of the main obstacles in the adoption of silicon carbide diodes is cost as it is five times costlier than silicon fast recovery diodes. In addition, silicon carbide is difficult to process compared to silicon. For instance, costly ion implementation is used for doping due to low diffusion rate. Also, reactive ion etching with fluorine based plasma is performed on silicon carbide diodes. This increases the cost and limits the device structures to be built.
Asia Pacific to lead the Global Market
- In terms of region, the silicon carbide diodes market can be divided into North America, Europe, Asia Pacific, South America, and Middle East & Africa
