DMG3420U-7 Description

Short technical summary and product information.

The DMG3420U-7 is an N-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It is designed for low on-state resistance and fast switching performance, making it suitable for power management applications. Key electrical specifications include a drain-source voltage (Vdss) of 20V, continuous drain current (Id) of 5.47A at Ta=25°C, and a maximum on-resistance of 29mOhm at Vgs=10V and Id=6A. The gate threshold voltage is 1.2V maximum at 250µA. The device features low input capacitance of 434.7pF at Vds=10V and a gate charge of 5.4nC at Vgs=4.5V, enabling efficient switching. The MOSFET is housed in a surface-mount SOT-23-3 package (also known as TO-236-3 or SC-59) and is rated for operation from -55°C to 150°C. It is RoHS3 compliant, halogen and antimony free, and has a moisture sensitivity level of 1. Typical applications include general-purpose interfacing switches and power management functions.
