FPF3380UCX Over-Voltage Protection Load Switch onsemi FPF3380UCX Over-Voltage Protection Load Switch contains an N-MOSFET that can operate over an input voltage range of 2.8V to 23V and support a maximum continuous current of 5A. The internal FET is turned off immediately to prevent damage to the protected downstream components when the input voltage exceeds the over-voltage threshold. The FPF3380UCX Switch has integrated ±110V surge protection TVS based on IEC61000-4-5 standards. The FPF3380 Over-Voltage Protection Load Switch is available in a small 12-bump WLCSP package and operates over the free-air temperature range of -40°C to +85°C.
