I. Automotive-Grade MOSFETs: Rigorous Certification, Suitable for High-Reliability Automotive Applications

Infineon’s automotive-grade MOSFETs (OptiMOS™, StrongIRFET™, and CoolSiC™ Automotive) are certified to AEC-Q101 and higher standards, with an operating temperature range of -55°C to +175°C. They feature low on-resistance, strong surge immunity and long-term stability, making them suitable for complex automotive operating conditions.

Key advantages: Full compliance with automotive electronics reliability standards; low RDS(on) reduces conduction losses; optimised packaging (TO-247, Q-DPAK, etc.) suits compact in-vehicle layouts; supports long-term operation in extreme environments such as high temperatures, high humidity and vibration.

Typical Applications: New energy vehicle on-board chargers (OBC), DC-DC converters, motor controllers, battery management systems (BMS), and body electronic load control, among others.

Representative Models: ISC040N04NM6, IPD60R600CM8, 750V CoolSiC™ automotive-grade series, etc.

II. Silicon Carbide (SiC) MOSFETs: Wide Bandgap Technology, the Benchmark for High Efficiency

Infineon’s CoolSiC™ silicon carbide MOSFETs utilise second-generation trench gate technology. Leveraging the high breakdown field strength and low-loss characteristics of SiC material, they overcome the performance limitations of traditional silicon-based devices and are the preferred choice for high-voltage, high-frequency applications.

Key advantages: Voltage ratings from 400V to 3300V; ultra-low switching losses that are temperature-independent; extremely low intrinsic body diode reverse recovery charge; gate voltage range of -10V to +25V, reducing the risk of false triggering; and compatibility with both high-frequency hard-switching and soft-switching topologies.

Typical Applications: Photovoltaic inverters, energy storage systems, AI server power supplies, electric vehicle charging stations, industrial high-voltage power supplies, UPS (uninterruptible power supplies), etc.

Representative Models: 650V/750V/1200V CoolSiC™ series (e.g. IMLT65R075M2H), full range of single transistors and power modules from Infineon.

III. N-Channel MOSFETs: Mainstream and Versatile, Comprehensive Coverage with Low Losses and High Efficiency

Infineon’s N-channel MOSFETs (OptiMOS™, CoolMOS™, StrongIRFET™) are the mainstream choice in power electronics, offering advantages such as low on-resistance, high switching speed and cost-effectiveness. With a voltage range of 20V–950V and a wide current range, they are suitable for the vast majority of power conversion applications.

Key advantages: OptiMOS™ (5th/6th/7th generation) focuses on ultra-low RDS(on), suitable for 48V data centre and telecommunications power supplies; CoolMOS™ super-junction technology (500V–950V) is suitable for high-voltage PFC and LLC topologies; StrongIRFET™ is suitable for high-current industrial drive applications.

Typical Applications: Industrial power supplies, server/telecom SMPS, LED lighting drivers, motor control, battery charge/discharge management, etc.

Representative Models: BSZ075N08NS5, SPB17N80C3, IRFP90N20DPBF, etc.

IV. P-Channel MOSFETs: Suitable for Negative Voltage, Preferred for Complementary Topologies

Infineon’s P-channel MOSFETs are designed for negative voltage circuits and complementary power topologies, featuring low on-resistance, low gate drive voltage and excellent thermal stability. They are suitable for applications such as power supply reverse polarity protection and load switching.

Key advantages: Voltage range from -20 V to -200 V; low on-resistance; packaging compatible with N-channel devices, facilitating PCB layout and complementary design; suitable for low-voltage, high-current reverse load control.

Typical Applications: Power management in portable devices, battery protection boards, reverse polarity switches, audio power amplification, and negative power supply circuits in industrial control systems.

Representative Models: IRF9540N, SPP45P06S, AUIRF4905, etc.
