48A, 100V, R
= 0.039Ω @V = 10 V
DS(on) GS
Low gate charge ( typical 48 nC)
Low Crss ( typical 85 pF)
Fast switching
100% avalanche tested
Improved dv/dt capability
This advanced technology is especially tailored to minimize
on-state
resistance,
provide
superior
switching
performance, and withstand high energy pulse in the
avalanche and commutation modes. These devices are
well suited for low voltage applications such as audio
amplifiers, high efficiency switching DC/DC converters, and
DC motor control.
