DMN3730U-7 Description

Short technical summary and product information.

The DMN3730U-7 is a 30V N-Channel Enhancement Mode MOSFET from Diodes Incorporated, designed for efficient power management in portable and load switch applications. It offers a maximum drain current of 0.94A at Vgs=4.5V and a low on-resistance of 460 mΩ (typical at Vgs=4.5V) and 560 mΩ at Vgs=2.5V. The device has a gate threshold voltage of 950 mV max, enabling direct drive from low-voltage logic. It features ESD protection up to 2 kV on the gate. Input capacitance is 64.3 pF and gate charge is 1.6 nC, supporting fast switching. Power dissipation is limited to 450 mW at ambient temperature. The MOSFET is housed in a surface-mount SOT23 package, weighing 0.08 grams, and is supplied in tape and reel with 3000 pieces per reel. It is fully RoHS compliant, lead-free, and halogen-free. Note: This part is not recommended for new designs; the suggested replacement is DMN3731U.
