Specifications

The FDD3706NL typically features a drain-source voltage (VDS) of 30V, a continuous drain current (ID) of around 16A, and an on-resistance (RDS(on)) of approximately 6.5 mΩ at VGS = 10V. It is available in a Power33 package. These specifications can vary slightly, so always consult the datasheet for the most accurate and up-to-date information. The gate threshold voltage is typically between 1V and 3V, making it suitable for logic-level driving. The device also exhibits a low gate charge, which further contributes to its fast switching performance. The maximum power dissipation is dependent on the thermal management of the application. Proper heatsinking is recommended to maintain device performance and reliability.
