FDMS1D4N03S Description

Short technical summary and product information.

This N-Channel power MOSFET is designed for high-efficiency switching applications. It offers a maximum drain-to-source voltage of 30 V and can handle a continuous drain current of 211 A at case temperature. The device features an ultra-low on-resistance of 1.09 mOhm (max) at a gate drive of 10 V and 38 A drain current. The gate charge is 65 nC at 4.5 V, and input capacitance is 10250 pF at 15 V drain-source bias.

 

The MOSFET integrates a Schottky diode body, which helps improve switching performance and reduce reverse recovery losses. It operates over a junction temperature range of -55°C to 150°C and dissipates up to 74 W at case temperature. The device is packaged in an 8-PowerTDFN (8-PQFN 5x6) surface-mount package, suitable for compact power system designs.

 

Typical applications include DC-DC converters, load switches, and power management in computing, telecom, and industrial systems requiring low conduction losses and high current handling. The recommended gate drive voltages are 4.5 V for minimum on-resistance and 10 V for optimized Rds(on).
