OptiMOS™ Linear FET
Combining a low RDS(on) with a wide safe operating area (SOA)
With Infineon’s OptiMOS™ Linear FET you can escape settling between on-state resistance (RDS(on)) and linear mode capability – operation in the saturation region of an enhanced mode MOSFET. The OptiMOS™ Linear FET revolutionary approach offers the state-of-the-art RDS(on) of a trench MOSFET together with the wide safe operating area (SOA) of a classic planar MOSFET.
This product is the perfect fit for hot-swap and e-fuse (electronic fuse) applications commonly found in telecom and battery management systems. OptiMOS™ Linear FET MOSFETs prevent damage at the load by limiting high in-rush currents.
Available in voltage classes of 60V, 80V, 100V, 150V and 200V, and in package types of D2PAK, D2PAK-7pin and TO-Leadless (TOLL), OptiMOS™ Linear FET reduce conduction losses, set up faster and have shorter intermissions.
