Description
- Low threshold voltage (VGS(th) ~1V), making it suitable for 3.3V or 5V logic systems.
- Low on-resistance (RDS(on) ~50mΩ at VGS=4.5V), reducing power loss.
- Compact SOT-23 package, ideal for space-constrained designs.
Common uses include power management, load switching, and battery-powered devices. Its fast switching speed and low gate charge enhance efficiency in DC-DC converters and portable electronics.
For detailed specs, refer to the datasheet or ON Semiconductor’s resources.
Equivalent
- FDN337N (Lower current rating)
- 2N7002 (Common SMD alternative)
- BS170 (Through-hole equivalent)
- DMN3404L (Similar specs)
- NDS7002A (Close match)
Check datasheets for exact compatibility, as voltage/current ratings may vary slightly.
Features
- Voltage Rating: 30V drain-source voltage (VDS).
- Current Handling: 2.7A continuous drain current (ID).
- Low On-Resistance: 50mΩ (max) at VGS = 10V.
- Gate Threshold Voltage: 1V (typical) for easy low-voltage drive.
- Fast Switching: Low gate charge (Qg = 8.5nC) for efficient performance.
- Power Efficiency: Low power loss due to minimal RDS(on).
- Package: SOT-23 (small form factor, suitable for compact designs).
- Applications: Power management, load switching, and DC-DC converters.
Compact, efficient, and ideal for low-voltage applications.
