Visão Geral
Description
- Voltage Rating: 20V (drain-to-source, VDSS).
- Current Rating: 3.7A (continuous drain current, ID).
- Low On-Resistance: 45mΩ (typical at VGS = 4.5V), reducing power loss.
- Logic-Level Gate Drive: Fully enhanced at 2.5V (VGS(th) ~1V), compatible with 3.3V/5V microcontrollers.
- Fast Switching: Low gate charge (QG ~8nC) for high-frequency applications.
- Package: SOT-23 (3-pin), compact for space-constrained designs.
Common Uses: Power management (DC-DC converters, load switches), battery protection, and portable electronics.
Advantages: Low cost, small footprint, and efficient performance in low-power circuits.
