The 89 nC typical gate charge at 10 V means the gate driver must source about 0.9 A peak to switch at 100 kHz — a standard automotive gate-driver IC handles that without extra buffering.","metaTitle":"Infineon AUIRFR4104TRL N-Channel MOSFET, 40 V, 42 A, HEXFET","metaDescription":"Infineon AUIRFR4104TRL automotive N-channel HEXFET MOSFET, 40 V, 42 A, 5.5 mOhm Rds(on).
