AO3402 Description

Short technical summary and product information.

The AO3402 is an N-Channel enhancement-mode MOSFET designed for low-voltage switching applications. It features a maximum drain-source voltage of 30V and a continuous drain current of 4A at 25°C ambient temperature. The device utilizes advanced trench technology to achieve a low on-resistance of 52 mΩ maximum at Vgs=10V and Id=4A, with even lower resistance at higher gate drives.

 

Key electrical characteristics include a gate threshold voltage range of 0.5V to 1.5V, making it suitable for logic-level drive. The device offers fast switching with typical turn-on delay of 3.5 ns and rise time of 1.5 ns. Input capacitance is 285 pF maximum at Vds=15V, and total gate charge is 12 nC maximum at Vgs=10V.

 

The AO3402 is packaged in a surface-mount SOT-23-3 package, suitable for automated assembly. It is designed for use in load switching and PWM applications where space is limited and efficiency is critical.
