FDS8978 Description

Short technical summary and product information.

The FDS8978 is a dual N-channel enhancement mode MOSFET designed for efficient power management in DC/DC converters. It features two independent MOSFETs in a single 8-SOIC package, offering a space-saving solution for synchronous rectification and switching applications.

 

Key electrical specifications include a maximum drain-source voltage of 30V and continuous drain current of 7.5A at 10V gate drive (6.9A at 4.5V). The on-resistance is typically 14mΩ and maximum 18mΩ at 10V gate bias, with a maximum of 21mΩ at 4.5V. The device supports logic level gate drive, allowing direct interface with low-voltage controllers.

 

The MOSFET incorporates trench technology for low gate charge (26nC typical) and fast switching. Gate threshold voltage ranges from 1.2V to 2.5V. Thermal characteristics include junction-to-case resistance of 40°C/W and junction-to-ambient of 78°C/W (on 0.5 in² copper pad).

 

Packaged in an 8-SOIC (0.154", 3.90mm width) surface mount package, the FDS8978 is RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity. It is suitable for battery management, load switching, and power supply designs.
