STL70N4LLF5 N-channel 40 V, 0.0055 , 18 A, PowerFLATTM (6x5) STripFETTM V Power MOSFET Preliminary Data Features RDS(on) Type VDSS ID max STL70N4LLF5 40 V 0.0065 18 A (1) 1. The value is rated according Rthj-pcb RDS(on) * Qg industry benchmark Extremely low on-resistance RDS(on) PowerFLATTM ( 6x5 ) High avalanche ruggedness Low gate drive power losses Application Switching applications Figure 1. Internal schematic diagram Description This product utilizes the 5th generation of design rules of ST's proprietary STripFETTM technology. The lowest available RDS(on)*Qg, in this chip scale package, makes this device suitable for the most demanding DC-DC converter applications, where high power density is to be achieved. Table 1.
