Présentation

Description

The AO3400A is a P-channel MOSFET designed for low-voltage, high-efficiency switching applications. Key features:
- Voltage Rating: -30V (Drain-to-Source).
- Current Handling: -4.3A (continuous).
- Low On-Resistance (RDS(on)): ~50mΩ (at VGS = -10V).
- Gate Threshold (VGS(th)): -1V (typical).
- Fast Switching: Optimized for power management in portable devices, load switches, and battery protection circuits.
Packaged in SOT-23, it’s compact and suitable for space-constrained designs. Common uses include DC-DC converters, power distribution, and reverse polarity protection.
Advantages: Low gate drive requirements, high efficiency, and robust performance in 3.3V/5V systems.
Note: Ensure proper gate voltage (VGS ≤ ±12V) to avoid damage.
For detailed specs, refer to the datasheet.
