The FDMS8558S is an N-Channel Power MOSFET manufactured by ON Semiconductor. It is designed for high-efficiency power management applications requiring low on-resistance and high current capability. The device features a maximum drain-source voltage of 25V and can handle continuous drain currents of 33A at 25°C ambient temperature (90A at case temperature). The typical on-resistance is an ultra-low 1.5 mΩ at 10V gate drive, minimizing conduction losses. The gate threshold voltage is 2.2V maximum, allowing logic-level drive. The total gate charge is 81 nC, and input capacitance is 5118 pF, enabling fast switching. The MOSFET is housed in an 8-PowerTDFN package (8-PQFN 5x6mm) for surface mount assembly. It operates over a junction temperature range of -55°C to 150°C. The device is RoHS3 compliant and has a moisture sensitivity level of 1. This combination of low resistance, high current, and compact package makes it suitable for DC-DC converters, load switches, and battery protection circuits.
