about Silicon Carbide Technology

Silicon Carbide (SiC) technology guides you to the next level of high power application design. Firstly, this technology provides stable low on-resistance and steady leakage current in a high-temperature environment. Secondary, it has a higher breakdown strength, fast reverse recovery, and a high avalanche ruggedness. Thirdly, there are many system benefits include reducing power loss, increasing operating temperature range, and reducing EMI. In conclusion, Silicon Carbide MOSFET relay series are ideal for automotive and industrial applications such as Battery Management System (BMS), Energy Storage System (ESS), Automated Test Equipment (ATE), and security equipment.
