DMN2990UFA-7B Description

Short technical summary and product information.

The DMN2990UFA-7B is a 20V N-Channel enhancement mode MOSFET designed for high efficiency power management applications. It features a maximum drain-source voltage of 20V and a continuous drain current of 510mA at 25°C. The device achieves a low on-resistance of 990mOhm at 4.5V gate drive, with increasing resistance at lower gate voltages: 1.2Ω at 2.5V, 1.8Ω at 1.8V, and 2.4Ω at 1.5V. The gate threshold voltage is a maximum of 1V, enabling low-voltage operation.

 

The MOSFET offers excellent switching performance with an input capacitance of 27.6pF and a gate charge of 0.5nC, making it suitable for high-speed switching. It is housed in a compact X2-DFN0806-3 surface mount package with a profile of only 0.4mm, significantly reducing board space compared to SOT23 packages. The device is qualified to AEC-Q101 standards for automotive reliability.

 

Key features include ESD protected gate, very low gate threshold voltage, and a total lead-free and RoHS compliant design. The package is halogen and antimony free, meeting green device requirements. The DMN2990UFA-7B is ideal for general purpose interfacing switches, power management functions, and analog switch applications.
