The FDB1D7N10CL7 is an N-Channel Shielded Gate POWERTRENCH® MOSFET manufactured by ON Semiconductor. This advanced MOSFET leverages ON Semiconductor's POWERTRENCH process, incorporating Shielded Gate technology to deliver minimized on-state resistance and superior switching performance with a high-quality soft body diode. The component features a maximum drain-to-source voltage (VDS) of 100 V and can handle continuous drain currents up to 268 A at 25°C. It boasts a low RDS(on) value of 1.7 mΩ at a gate-to-source voltage (VGS) of 12 V and drain current (ID) of 100 A, making it highly efficient for power management applications. Key applications include industrial motor drives, power supplies, automation, battery-operated tools, solar inverters, and energy storage systems. The FDB1D7N10CL7 is housed in a robust D2PAK7 (TO-263 7 LD) package and is designed to withstand a wide range of operating temperatures from -55°C to +175°C.
