概述

Features

The AO3407 is a P-channel MOSFET with the following key features:
- Voltage Rating: -30V drain-to-source (V_DS).
- Current Rating: -4.3A continuous drain current (I_D).
- Low On-Resistance (R_DS(on)): 50mΩ max at V_GS = -10V.
- Gate Threshold (V_GS(th)): -1V to -2.5V.
- Fast Switching: Low gate charge (Q_g) for efficient performance.
- Package: SOT-23 (compact surface-mount).
- Applications: Power management, load switching, battery protection.
Ideal for low-voltage, high-efficiency circuits.

Pinout

The AO3407 is a P-channel MOSFET with 3 pins (SOT-23 package):
1. Gate (G): Controls the switching operation.
2. Source (S): Connected to the input voltage (typically higher potential for P-channel).
3. Drain (D): Output connection to the load.
Key Functions:
- Voltage Rating: -30V (D-S).
- Current: -4.3A (continuous).
- Low RDS(on): ~40mΩ (at VGS = -10V).
- Logic-Level Gate Drive: Efficient switching at low voltages (VGS ≥ -2.5V).
Commonly used for power switching, load control, or reverse polarity protection in low-voltage circuits.
