OptiMOS™ 6 power MOSFET 40 V normal level with latest Infineon technology in a SuperSO8 package This best-in-class OptiMOS™6 power MOSFET 40 V normal level, featuring very low RDS(on) of 0.7mOhm, offers a benchmark solution for normal level (higher threshold voltage) applications such as battery-powered applications, battery-powered tools, battery management, and low voltage drives. A higher Vth for the normal level portfolio means that only larger gate voltage spikes would cause an unwanted turn-on.
