ONSEMI FQB55N10 Power MOSFET

The FQB55N10 is a QFET® N-channel enhancement-mode Power MOSFET manufactured using planar stripe and DMOS technology. Designed to minimize on-state resistance, it offers excellent switching performance and high avalanche energy capability. This device is ideal for use in switched-mode power supplies, active power factor correction (PFC) circuits, and electronic lamp ballasts. It is 100% avalanche tested, with a typical gate charge of 75 nC and a typical reverse transfer capacitance (Crss) of 130 pF. Due to high market demand, lead times may be extended, and delivery dates are subject to fluctuation. The product is exempt from discounts.
