Product details

The Texas Instruments CSD18510KTTT is a 40 V N-channel NexFET power MOSFET in a DDPAK/TO-263-3 surface-mount package. This combination of low on-resistance and high current capability makes it suited for high-efficiency power switching in motor drives, DC-DC converters, and battery protection circuits.

The 40 V drain-source voltage (Vdss) sets the maximum bus voltage this MOSFET can block.

The DDPAK/TO-263-3 (D²Pak) is a surface-mount package with a large exposed drain tab for heat sinking. The tab is electrically connected to the drain, so the PCB copper pour must be sized for both thermal dissipation and electrical clearance. The three-lead plus tab footprint is standard for high-current TO-263 devices; verify the land pattern matches the supplier device package (DDPAK/TO-263-3) before layout.

It is ROHS3 compliant.
