An N-channel MOSFET uses electrons to create a current channel. This allows electrons to move quickly and easily through the current when the MOSFET is activated and switched on. Because of the specific characteristics of N-channel MOSFETs, the mobility of the carriers is approximately two to three times higher than that of a P-channel for the same RDS(on) value, and the P-channel chip must be two to three times the size of the N-channel. For this reason, using MOSFET transistor N-channels for high current applications is often the preferred choice.
Infineon's OptiMOS™ N-channel power MOSFETs were developed to increase efficiency, power density, and cost-effectiveness. Designed for high-performance applications and optimized for high switching frequencies, OptiMOS™ products offer the industry's best figure of merit.
Now complemented by StrongIRFET™ and StrongIRFET™ 2 N-channel MOSFETs, this extended portfolio creates a truly compelling combination. StrongIRFET™ and StrongIRFET™ 2 N-channel power MOSFETs add robust design and excellent price/performance to the best-in-class technology of OptiMOS™ MOSFETs. Both product families meet the highest quality and performance demands.
The CoolMOS™ N-Channel MOSFET product range targets a broad range of applications from low power to higher power levels. Furthermore, the automotive qualified superjunction (SJ) MOSFETs offer the highest reliability in the field and are compliant with automotive lifetime requirements.
