| STL28NF3LL N-CHANNEL 30V - 0.0055 - 28A PowerFLATTM LOW GATE CHARGE STripFETTM MOSFET PRELIMINARY DATA TYPE STL28NF3LL s s s VDSS 30 V RDS(on) < 0.0065 ID 28 A TYPICAL RDS(on) = 0.0055 IMPROVED DIE-TO-FOOTPRINT RATIO VERY LOW PROFILE PACKAGE DESCRIPTION This Power MOSFET is the second generation of STMicroelectronics unique "STripFETTM" technology. The resulting transistor shows extremely low onresistance and minimal gate charge. The new PowerFLATTM package allows a significant reduction in board space without compromising performance.
