Overview
Description
- Voltage Rating: -30V (VDSS).
- Current Rating: -4.3A (ID).
- Low On-Resistance: 36mΩ (max) at VGS = -10V.
- Gate Threshold: -1V (typical), enabling compatibility with 3.3V/5V logic.
Commonly used in power management, load switching, and battery protection circuits, the AO3413 is favored for its compact SOT-23 package and fast switching speed. It’s ideal for portable devices, DC-DC converters, and low-side switching where space and efficiency are critical.
Advantages:
- Low gate drive requirements.
- High power density.
- Cost-effective for mass production.
