IRLML6402 3.7A 20V P-Channel MOSFET SOT-23 SMD

The IRLML6402 is a P-channel enhancement-mode MOSFET in a compact SOT-23 surface-mount package, specified for switching and load-control tasks where a small footprint and PCB space savings are important. With a 20V maximum rated voltage and a 3.7A current designation in the product name, it is suitable for low-voltage, moderate-current applications that require a P-channel device for high-side switching, reverse polarity protection, or simple level-shifting circuits. Its SOT-23 SMD package makes the device convenient for automated assembly and dense board layouts. P-channel topology simplifies high-side switch implementations by allowing the source to connect to the positive rail and the drain to the load, reducing the need for gate-boost circuitry in many designs. The device can be used in battery-powered equipment, portable electronics, power-path control, and small motor or LED drivers where a compact high-side switch is required. Designers should consult the official datasheet for detailed electrical characteristics, thermal limits, recommended PCB layout practices, and safe operating area information to ensure the device meets their application's requirements. Proper gate drive, heat dissipation, and verification under actual operating conditions are recommended before final deployment.
