Automotive electronics cover Electric Vehicles (EV), Hybrid Electric Vehicles (HEV), On-Board Chargers (OBC), DC-DC converters, motor drive systems, automotive power modules, and various safety control systems. Design in this field must meet strict requirements for high reliability (AEC-Q certification), wide operating temperature range (-40°C to 175°C), high-efficiency energy conversion, and anti-interference capabilities. As automotive voltage levels rise (e.g., 400V / 800V platforms), SiC components (such as SiC MOSFET and SiC SBD) have become key technologies for high-voltage, high-efficiency power conversion. They effectively reduce switching loss, improve energy utilization, and reduce heat dissipation requirements. Combined with protection components like TVS and Zener Diode, they ensure the system can withstand transient surges (such as Load Dump) and Electrostatic Discharge (ESD).
