Visão Geral
Features
- Voltage Rating: -30V drain-to-source (VDS).
- Current Rating: -4.3A continuous drain current (ID).
- Low On-Resistance (RDS(on)): 50mΩ max at VGS = -10V.
- Gate Threshold (VGS(th)): -1V to -2.5V.
- Fast Switching: Low gate charge (Qg) for efficient performance.
- Package: SOT-23 (compact surface-mount).
- Applications: Power management, load switching, battery protection.
Ideal for low-voltage, high-efficiency circuits.
Pinout
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.

Application
1. Power Management – Switching and load control in portable devices.
2. Battery Protection – Reverse polarity and discharge circuits.
3. DC-DC Converters – Efficient power conversion in low-voltage systems.
4. Load Switching – On/off control in USB peripherals and IoT devices.
5. Motor Drivers – Small motor control in consumer electronics.
Its low on-resistance (RDS(on)) and compact SOT-23 package make it ideal for space-constrained, low-power applications.
