The FDFS6N303 is an N-Channel MOSFET with an integrated Schottky diode, manufactured by On Semiconductor (formerly Fairchild Semiconductor). It features a drain-source breakdown voltage of 30V and a continuous drain current rating of 6A at 25°C. The static drain-source on-resistance is typically 0.025Ω at VGS=10V and 0.043Ω at VGS=4.5V, with maximum values of 0.035Ω and 0.055Ω respectively. The gate threshold voltage ranges from 1V to 3V, allowing drive from low-voltage logic.
This device incorporates a high cell density MOSFET and a low forward drop Schottky diode (VF <0.28V at 0.1A) in a single surface mount package. The MOSFET and Schottky diode are electrically isolated within the package. The general-purpose pinout provides design flexibility for various switching applications.
The FDFS6N303 is particularly suited for DC/DC converter topologies such as buck, boost, synchronous, and non-synchronous converters. It offers fast switching with typical turn-on delay of 7.5ns and turn-off delay of 13ns. The input capacitance is 350pF maximum, and total gate charge is 17nC maximum at VGS=10V.
The device is housed in an 8-SOIC (0.154", 3.90mm Width) surface mount package, with a supplier device package of 8-SOIC. Power dissipation is rated at 1.6W for single operation and 2W for dual operation at 25°C ambient. The operating junction temperature range is -55°C to 150°C.
