IRFP340 N-Channel Power MOSFET: 400V Limits & 0.55 Ohm Rds(on)

High-power switching networks need solid mechanical stability alongside tight electrical control. The IRFP340 N-channel power MOSFET provides reliable power management with a 400V drain-to-source rating and an 11A continuous drain current capacity. Housed in a through-hole TO-247AC footprint, the IRFP340 uses an isolated central mounting hole that improves lead creepage distances to help prevent high-voltage arcing. A low static on-resistance of 0.55 Ω minimizes heat dissipation during steady operation, while its 150W total power rating keeps system thermals balanced under continuous load. Built with dynamic dV/dt withstand and repetitive avalanche endurance, it guards control logic against inductive voltage spikes. Design teams choose this transistor for high-frequency DC-DC converters, off-line switch-mode power supplies, and industrial motor drives.
