FDS3170N7 Description

Short technical summary and product information.

The FDS3170N7 is a 100V N-Channel PowerTrench MOSFET manufactured by On Semiconductor. It is designed for use in DC/DC converters and synchronous rectifier circuits, offering low on-resistance and fast switching. The device is rated for a maximum drain-source voltage of 100V and a continuous drain current of 6.7A at 25°C ambient, with a pulsed drain current rating of 60A.

 

The MOSFET features a typical RDS(on) of 26mΩ at VGS=10V, with a maximum of 28mΩ, and a gate threshold voltage ranging from 2V to 4V. Total gate charge is 55nC typical (77nC maximum), contributing to efficient high-frequency switching. Thermal characteristics include a maximum power dissipation of 3W at 25°C ambient and a junction-to-ambient thermal resistance of 40°C/W.

 

The FDS3170N7 is offered in an 8-SOIC surface-mount package with a supplier device package of 8-SO, suitable for automated assembly. It is available in tape-and-reel packaging with 2500 units per reel. The operating junction temperature range is -55°C to +150°C. The part is listed as RoHS3 compliant.
