MDD50N03D AI Analysis:
Datasheet, Specs, Alternatives & ECAD

It features a 30V VDS, 50A ID, and a maximum RDS(on) of 9mΩ at 10V. It is housed in a TO-252 package.

It is commonly used in load switching, uninterruptible power supplies (UPS), and high-frequency power circuits.

Engineers should review the thermal resistance (RθJC = 4.4°C/W) and ensure the PCB layout supports adequate heat dissipation for the 28W power dissipation rating.

The part is currently active and widely available through major distributors, with no immediate end-of-life concerns reported.
