Automotive power steering system design engineers are demanding solutions that deliver improved efficiency and power control characteristics. Fairchild Semiconductor's (NYSE: FCS) 40V N-channel PowerTrench® MOSFET helps designers address these technical challenges.

The FDB9403 utilizes Fairchild's shielded-gate technology to improve resistance characteristics while reducing capacitance. The device offers a 20% lower RDS(ON) than the nearest competitor, as well as a low Qg value that reduces power consumption and ultimately improves overall efficiency. The FDB9403 MOSFET is a basic switch for current control, optimized for electronic power steering, suspension control, and power train management applications because it controls it efficiently without consuming power.

Features and Benefits:

• Typ RDS(ON) = 1mΩ at VGS = 10V, ID = 80A for reduced power consumption and improved efficiency.
• Typ Qg(tot) = 164nC at VGS = 10V, ID = 80A to reduce power consumption for improved efficiency
• UIS performance
• RoHS compliant and AEC Q101 certified
