FDD8778 Description

Short technical summary and product information.

The FDD8778 is an N-Channel PowerTrench MOSFET designed by ON Semiconductor. It is optimized for DC/DC converters using synchronous or conventional PWM controllers, offering low gate charge, low on-resistance, and fast switching speed.

 

Key specifications include a drain-source voltage rating of 25V, continuous drain current of 35A, and maximum on-resistance of 14.0mΩ at VGS=10V. The device features a typical gate charge of 12.6nC, making it suitable for high-efficiency power conversion.

 

Packaged in a TO-252AA (DPAK) surface-mount package, the FDD8778 operates over a junction temperature range of -55°C to +175°C. It is RoHS compliant and lead-free, meeting environmental standards.

 

Typical applications include DC-DC converters for desktop computers and servers, as well as voltage regulator modules for intermediate bus architecture. The MOSFET is also available in the TO-251AA (I-PAK) package as the FDU8778 variant.
