The DMN3731UFB4-7B is a 30V N-Channel Enhancement Mode MOSFET designed by Diodes Incorporated for high-efficiency power management. It features a maximum drain-source voltage of 30V and a continuous drain current of 1.2A at 25°C (0.9A at 70°C). The device is optimized for low on-resistance, with 460mOhm typical at Vgs=4.5V and 560mOhm at Vgs=2.5V, ensuring minimal conduction losses in battery-powered applications.
This MOSFET is housed in an ultra-compact X2-DFN1006-3 surface-mount package with a 0.4mm profile, offering a footprint ten times smaller than a standard SOT23. It supports a gate drive voltage as low as 1.8V, making it suitable for direct battery driving. The device also includes ESD protection on the gate and is fully RoHS, Halogen-Free, and Antimony-Free compliant. Operating temperature range is -55°C to 150°C.
Typical applications include load switching, portable electronics, and power management functions. The device offers low gate charge (5.5nC) and low input capacitance (73pF) for efficient switching at moderate frequencies. With MSL Level 1 moisture sensitivity and UL 94V-0 flammability rating, it is designed for robust and reliable operation in space-constrained designs.
