WSD4070DN33 AI Analysis:
Specs, Applications & Alternatives

It is primarily used in high-frequency point-of-load synchronous buck converters (MB/NB/UMPC/VGA), networking DC-DC power systems, and as a load switch.

Key specs include a 40V drain-source voltage, 68A continuous drain current, and a maximum RDS(ON) of 5.5mΩ at 10V gate drive.

Engineers should focus on thermal dissipation, as the device is small (DFN3X3-8L). Proper PCB copper area is required to meet the thermal resistance ratings.

Yes, it is an active, RoHS-compliant component designed for standard power electronics manufacturing.

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.
