FQP17N40 Description

Short technical summary and product information.

The FQP17N40 is an N-Channel enhancement mode power MOSFET manufactured by On Semiconductor using their proprietary planar stripe and DMOS technology. It is designed to offer low on-state resistance and superior switching performance combined with high avalanche energy capability.

 

Key electrical ratings include a 400V maximum drain-source voltage and a continuous drain current of 16A at 25°C case temperature. The device features a maximum drain-source on-resistance of 270 milliohms at a gate drive of 10V and a typical gate charge of 45nC, making it suitable for efficient switching applications. The MOSFET is also 100% avalanche tested, with a single pulsed avalanche energy rating of 1000mJ.

 

The FQP17N40 is supplied in a TO-220-3 through-hole package, allowing for easy mounting on heatsinks for thermal management. It is Pb-Free and suitable for use in switched-mode power supplies, active power factor correction circuits, and electronic lamp ballasts.
