Description

The MMQA27VT1G is a P-channel MOSFET from ON Semiconductor, designed for low-voltage, high-efficiency switching applications. Key features include:
- Voltage Rating: -20V (Drain-Source)
- Current Rating: -4.3A (Continuous Drain)
- Low On-Resistance (RDS(on)): 47mΩ (max) @ VGS = -4.5V
- Fast Switching: Optimized for power management in portable devices, load switches, and DC-DC converters.
- Compact Package: SOT-23 (3-pin), suitable for space-constrained designs.
Ideal for battery-powered systems, power distribution, and low-side switching, it offers efficient performance with minimal power loss.
For detailed specs, refer to the datasheet.
