FQP15P12/FQPF15P12 QFET FQP15P12/FQPF15P12 120V P-Channel MOSFET General Description These P -Channel enhanc ement m ode pow er f ield effect transistors ar e prod uced using F airchild’s proprietary, planar stripe, DMOS technology. This advanced technology has been especially t ailored to minimize on-st ate resist ance, provide superior swit ching performance, and wit hstand high energy pulse in t he avalanche and commutation mode. These devices are well suited for low voltage applications such as audio amplifier, high efficiency switching DC/DC converters, and DC motor control. ® Features • • • • • • • -15A, -120V, RDS(on) = 0.2Ω @VGS = -10 V Low gate charge ( typical 29 nC) Low Crss ( typical 110 pF) Fast switching 100% avalanche tested Improved dv/dt capability 17 [ ... ]
