200 V N-channel MOSFET for switched-mode and linear applications
The Infineon IRF6641TRPBF is a 200 V N-channel HEXFET power MOSFET rated for 4.6 A continuous drain current and a maximum Rds(on) of 59.9 mOhm at 10 V gate drive. The surface-mount package fits standard reflow assembly, and the 150 °C junction temperature rating gives headroom in hot environments such as enclosed power supplies or industrial control cabinets.
At 5.5 A drain current and 10 V gate drive, the maximum on-resistance is 59.9 mOhm. Conduction loss at 5.5 A is within the 2.8 W package power dissipation rating with adequate PCB copper and airflow.
There is no last-time-buy window, no end-of-life notice to track.
Mounting and thermal notes
Surface-mount package — no through-hole leads. For continuous operation near 4.6 A, plan for adequate copper on the drain connection to keep junction temperature below 150 °C.
