The FQPF19N10 is a 100V N-channel MOSFET that uses Fairchild's proprietary planar stripe DMOS technology. It has low on-state resistance, high switching performance, and the ability to withstand high-energy pulses in avalanche and commutation mode. It is suitable for low-voltage applications such as audio amplifiers, high-efficiency switching DC/DC converters, and DC motor control.
