Abstract: As the global electric vehicle (EV) market penetration continues to rise, the 800V high-voltage platform has become the industry standard, posing rigorous challenges in terms of voltage withstand capability, high-temperature resistance, and switching efficiency for power semiconductors. As an authorized distribution partner of STMicroelectronics (ST), Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada Electronics”) recently announced that it is steadily supplying the high-performance automotive-grade silicon carbide (SiC) power MOSFET—SCT020HU120G3AG—to global customers, helping enterprises overcome energy efficiency bottlenecks in high-voltage fast-charging and electric drive systems.
Technological Frontier: Third-Generation SiC Technology Powers 800V High-Voltage Platforms
The SCT020HU120G3AG is a high-performance product developed by STMicroelectronics based on advanced third-generation SiC MOSFET innovation technology. Against the backdrop of the current pursuit in new energy vehicles for “charging as fast as refueling,” the launch of this device addresses the pain points of core components in high-voltage architectures.
This device features a unique HU3PAK package, with a drain-source voltage of 1200V and a continuous drain current capability of up to 100A. Its most notable characteristic is its extremely low on-resistance, with a typical value of just 18.5 mΩ (18.5 milliohms). This low resistance remains stable across the entire operating temperature range, significantly reducing conduction losses.
Key Performance Highlights:
High-Speed Switching and High Efficiency: The SCT020HU120G3AG features ultra-low capacitance and very high switching frequencies, significantly enhancing the power density of on-board chargers (OBCs) and DC-DC converters, thereby reducing system size and weight.
Robustness and Reliability: The device incorporates an ultra-fast and stable intrinsic diode with excellent avalanche resistance. More importantly, it strictly complies with the AEC-Q101 automotive standard and supports a maximum junction temperature (Tj) of 200°C, making it perfectly suited for the harsh thermal environments of automotive powertrains.
Functional Safety Support: The device is equipped with a source sensing pin, a design that helps improve conversion efficiency and enables more precise monitoring in gate drive control.
Application Scenarios: Comprehensive Coverage from Electric Drive to Charging
With its superior performance, the SCT020HU120G3AG primarily targets the high-end automotive electronics market. Key application areas include:
Main Drive Inverters: Used for electric vehicle main motor drives, representing the most valuable application scenario for SiC devices.
On-Board Chargers: Supports bidirectional charging to reduce charging time.
DC/DC converters: High-efficiency conversion between high-voltage battery packs and low-voltage storage batteries.
