FDS8949 Description

Short technical summary and product information.

The FDS8949 is a dual N-channel MOSFET designed for efficient power switching in space-constrained applications. It features a logic-level gate, allowing direct drive from low-voltage logic circuits. With a maximum drain-source voltage of 40V and continuous drain current of 6A, it suits a variety of low-to-medium power switching tasks.

 

The device offers a low on-resistance of 29 mOhm maximum at 6A and 10V gate drive, minimizing conduction losses. Gate charge is 11 nC maximum at 5V, and input capacitance is 955 pF maximum at 20V, enabling fast switching. Power dissipation is rated at 2W.

 

Packaged in an 8-SOIC (0.154", 3.90mm width) surface-mount package, the FDS8949 is suitable for automated assembly. The operating junction temperature range is -55°C to 150°C. This MOSFET array integrates two independent N-channel transistors in a single package, saving board space.
