The Vishay IRFSL11N50APBF is a single N-channel power MOSFET, designed for use in switch-mode and linear power supplies, DC-DC converters, motor control, solid state relays, and other related applications. It is housed in a standard TO-247 package, and is constructed of a high-performance silicon material and has a low gate threshold voltage, making it suitable for low-voltage power control applications. Additionally, the IRFSL11N50APBF has a maximum drain-source on-state resistance (RDS(on)) of 11 mOhm, making it capable of delivering high power with low losses. It is also rated at a drain source voltage (Vds) of 500 V and a continuous drain current (Id) of 11A, making it suitable for DC-DC applications.
