P-Channel MOSFET 40V 10.5A TO-252 (DPAK) Surface Mount

The DMP4051LK3-13 from Diodes Inc. is a P-channel enhancement mode MOSFET, engineered to minimise on-state resistance (RDS(ON)) while delivering superior switching performance. This makes it an excellent choice for high-efficiency power management applications, including backlighting, DC-DC converters, and general power management functions.

This MOSFET is designed for fast and reliable operation. It features a low on-resistance of only 0.051 ohm maximum, ensuring minimal power loss during conduction. The device is fully tested in production with a 100% unclamped inductive switch (UIS) test, confirming its robustness and reliability in demanding environments.
