What the DMG2302 does

The DMG2302UK is an N-channel enhancement mode MOSFET available in SOT23 packages. It features a 20 V drain-source breakdown voltage, 2.8 A continuous drain current, and 120 mΩ on-resistance at 2.5 V gate drive. The device supports 12 A pulsed current and operates from -55 to +150 °C. Engineers typically use this component for high efficiency power management, DC-DC converters, and motor control applications requiring fast switching speed and low input capacitance.
