FQP6N40CF Description

Short technical summary and product information.

The FQP6N40CF is a high-voltage N-Channel MOSFET designed for power switching applications. Manufactured by On Semiconductor, this device offers a maximum drain-source voltage of 400V and a continuous drain current of 6A at case temperature. Its on-resistance (Rds(on)) is specified at a maximum of 1.1Ω with a gate drive of 10V and Id=3A, ensuring efficient operation. The gate threshold voltage is up to 4V at 250µA, and the device can handle a maximum gate-source voltage of ±30V. With an input capacitance of 625pF at Vds=25V and a total gate charge of 20nC at Vgs=10V, the FQP6N40CF is suitable for moderate-frequency switching. The power dissipation is rated at 73W at case temperature. The device is housed in a standard TO-220-3 through-hole package, making it easy to mount on heatsinks. It operates over a junction temperature range of -55°C to 150°C. The FQP6N40CF is suitable for applications such as switch-mode power supplies, motor control, and general-purpose power switching where high voltage and moderate current are required.
