FQA9N90C Description

Short technical summary and product information.

The FQA9N90C is a 900V N-Channel MOSFET designed for high-efficiency switched-mode power supplies, active power factor correction, and electronic lamp ballasts. It features a maximum continuous drain current of 9A at 25°C case temperature and 5.7A at 100°C. The on-resistance is 1.4Ω maximum at Id=4.5A, Vgs=10V. The device offers low gate charge (typical 45nC, maximum 58nC) and low reverse transfer capacitance (typical 14pF) for improved switching performance. It is 100% avalanche tested with a single pulsed avalanche energy rating of 900mJ. The MOSFET is housed in a TO-3P-3 (SC-65-3) through-hole package, allowing for efficient heat dissipation with a junction-to-case thermal resistance of 0.45°C/W. The operating junction temperature range is -55°C to 150°C.
