The FDS8638 is an N-Channel power MOSFET from On Semiconductor designed for efficient power switching applications. It features a maximum drain-to-source voltage (Vdss) of 40V and a continuous drain current rating of 18A at ambient temperature (Ta). The device achieves a low on-state resistance (Rds(on)) of 4.3mΩ maximum when driven with a 10V gate-source voltage at 18A, making it suitable for applications requiring high efficiency and minimal conduction losses.
The MOSFET supports gate drive voltages of 4.5V and 10V, with a maximum gate-source voltage rating of ±20V. The gate threshold voltage (Vgs(th)) is 3V maximum at a drain current of 250µA. Input capacitance (Ciss) is 5680pF maximum at Vds = 15V, and total gate charge (Qg) is 86nC maximum at Vgs = 10V, providing moderate switching performance for medium-frequency power conversion.
The device is housed in an industry-standard 8-SOIC (0.154", 3.90mm Width) surface mount package, with a supplier device package designation of 8-SOIC. It operates over a junction temperature range of -55°C to 150°C, with a maximum power dissipation of 2.5W at ambient temperature. The FDS8638 is suitable for load switching, DC-DC converters, and other power management circuits in space-constrained designs.
