The AO3442 is an N-channel MOSFET from Alpha & Omega Semiconductor designed for applications requiring 100V drain-source voltage handling and 1A continuous drain current at 25°C ambient. The device features a maximum drain-source on-resistance of 630 mΩ at VGS=10V and ID=1A, and 720 mΩ at VGS=4.5V and ID=0.8A, enabling efficient switching in low-power circuits.
The MOSFET supports gate-source voltages up to ±20V and has a gate threshold voltage range of 1.7V to 2.9V. It offers fast switching with typical turn-on delay of 5ns, rise time of 4ns, turn-off delay of 12ns, and fall time of 5ns. The device also includes a body diode with 0.9V typical forward voltage and 52ns reverse recovery time.
The AO3442 is suitable for boost converters, synchronous rectifiers, and power management circuits in consumer, telecom, and industrial applications. Its low gate charge (2.8nC typical at VGS=10V) helps minimize switching losses in high-frequency designs.
The device comes in a surface-mount SOT-23-3 package and operates over a junction temperature range of -55°C to 150°C. Maximum power dissipation is 1.4W at 25°C ambient temperature.
