OptiMOS™ 6 power MOSFET 135 V Normal Level in PQFN 3.3x3.3 package OptiMOS™ 6 135 V targets high-power motor-drive applications such as LEVs, e-forklifts, power and gardening tools, but also UPS applications which predominantly use 72-84 V batteries. This product effectively bridges the gap between the 120 V and 150 V MOSFETs and provides significant improvements in RDS(on) and cost, helping improve the system efficiency.
