The FDN372S is a 30V N-channel power MOSFET from Fairchild Semiconductor. It features low on-resistance and low gate charge, making it ideal for use in DC-DC converters and motor drives.
The FDN372S PowerTrench SyncFET integrates a MOSFET and a Schottky diode in a single 30 V component, making it suitable as the low‑side switch in synchronous DC‑DC converters and motor‑drive applications. It maximizes power‑conversion efficiency with low on‑resistance and low gate charge.
Key specifications include a 30 V drain‑source rating, +16 V gate‑source rating, 2.6 A continuous drain current, 0.5 W power dissipation, and thermal resistances of 250 °C/W (junction‑to‑ambient) and 75 °C/W (junction‑to‑case). The device is supplied in a SuperSOT™3 package marked FDN372S.
