AO3400A Overview
The AO3400A from Alpha & Omega Semiconductor is a 30 V N-channel MOSFET in a SOT-23 package built on trench technology for very low on-resistance. With RDS(on) under 32 mΩ at 4.5 V and under 48 mΩ at 2.5 V gate drive, it switches directly from logic-level signals in load-switch and PWM circuits.
Key Features
- 30 V drain-source voltage, ±12 V gate-source
- 5.7 A continuous drain current at TA = 25 °C, 30 A pulsed
- RDS(on) < 26.5 mΩ at VGS 10 V
- RDS(on) < 32 mΩ at 4.5 V and < 48 mΩ at 2.5 V
- Gate threshold 0.65 V to 1.45 V
- 1.4 W power dissipation at TA = 25 °C
Applications
- Load switches
- PWM applications
- Logic-level low-side switching
