A remote power controller (RPC) includes a line connection; a load connection; a first field effect transistor (FET) and a second FET arranged in parallel between the line connection and the load connection, wherein the first FET has a lower safe operating area (SOA) than a SOA of the second FET, and wherein the first FET has a lower resistance at saturation (RDS(on)) than the second FET; and a voltage offset element connected between the first FET and the second FET, such that in the event that a current in the RPC is above a current limiting setpoint, the voltage offset element is configured to cause the first FET to turn off.
