CoolMOS belongs to the family of high-voltage MOSFETs but stands out for its unique Super Junction Technology. Unlike traditional MOSFETs, which face a trade-off between on-resistance (Rds(on)) and breakdown voltage, CoolMOS integrates a vertically stacked p-n column structure in the drift region. This design dramatically reduces the resistance per unit area, allowing for lower conduction losses while maintaining high voltage ratings (typically 600V to 1200V). The result? Enhanced energy efficiency, improved thermal performance, and smaller device sizes—ideal for modern power systems demanding both power density and reliability.
Ultra-Low Conduction Losses
The Super Junction structure minimizes Rds(on) by up to 70% compared to conventional MOSFETs at the same voltage class. For example, a 650V CoolMOS can achieve an Rds(on) as low as 20 mΩ in a compact package, significantly reducing energy waste during current flow. This is critical for applications like AC-DC power supplies, where minimizing heat dissipation boosts overall system efficiency.
High-Speed Switching Capability
CoolMOS features low gate charge (Qg) and output capacitance (Coss), enabling fast switching speeds with minimal switching losses. This makes it perfect for high-frequency applications such as solar inverters, induction heating, and motor drives, where rapid on/off cycles are essential for performance.
Superior Thermal Management
The optimized cell design enhances heat dissipation, allowing the device to operate at lower temperatures even under heavy loads. This not only extends the lifespan of the component but also reduces the need for bulky heat sinks, contributing to more compact and cost-effective system designs.
Reliability Under Stress
CoolMOS is engineered to withstand harsh operating conditions, including voltage spikes and temperature fluctuations. Its robust avalanche capability and stable threshold voltage ensure consistent performance in challenging environments, such as electric vehicle (EV) chargers and industrial power systems.
Power Supplies: High-efficiency adapters, server power, and LED lighting drivers benefit from reduced losses and smaller form factors.
Renewable Energy: Solar inverters and wind turbines require reliable high-voltage switching, where CoolMOS excels in converting DC to AC with minimal waste.
Electric Vehicles: On-board chargers, DC-DC converters, and motor controllers in EVs demand high power density and efficiency, making CoolMOS an ideal choice.
Industrial Equipment: Motor drives, UPS systems, and welding machines leverage CoolMOS for its durability and high-frequency operation.
