Silicon Carbide: The Third-Generation Semiconductor Material

Silicon carbide is a typical third-generation semiconductor material. Compared with previous silicon materials, silicon carbide has the advantages of high breakdown field strength and high thermal conductivity, making it more suitable for high-voltage, high-frequency, and high-power scenarios. Silicon carbide has a stable crystal structure; even in high-temperature environments exceeding 300°C, it breaks through the parameter bottlenecks of devices made from traditional materials, directly promoting the upgrading of industries such as new energy.

Common Silicon Carbide Devices

Common SiC devices include diodes and MOSFETs, which are the two most widely used types. Silicon carbide MOSFETs integrate planar gate and trench gate process technologies, offering advantages such as fast switching speed, low loss, high voltage and large current capability, and strong high-temperature stability. Currently, they are mainly applied in fields such as new energy vehicle main inverters and energy storage converters, where they can reduce energy consumption and extend service life. However, the manufacturing cost of silicon carbide MOSFETs is currently high, and the process precision requirements are strict, making large-scale popularization still challenging.

Silicon Carbide Diodes

Silicon carbide diodes feature reverse recovery current characteristics, so they are widely used in high-frequency scenarios such as photovoltaic inverters and on-board chargers. Heketai's silicon carbide diode model HSCF10D65, with a voltage rating of 650V, boasts ultra-low reverse leakage current and ultra-low switching charge. It is applied in the MPPT circuits and inverter bridge arms of micro-inverters, capable of matching high-frequency switching frequencies above 50kHz. Compared with silicon-based diodes, silicon carbide diodes improve efficiency conversion by 1.5% to 2% and have no reverse recovery loss.

Summary

Silicon carbide devices exhibit ultra-high tolerance to high voltage, high frequency, and high temperature, breaking through the physical limits of traditional silicon-based devices. They help industries such as new energy vehicles achieve comprehensive improvements in energy efficiency, miniaturization, and reliability. The technology for silicon carbide diodes is mature, and they have become widely used commercial devices. Heketai's silicon carbide diode products have sufficient production capacity and can be supplied in batches; enterprises are welcome to purchase them.
