The MCR12NG series of field-effect transistors (FETs) from ON Semiconductor are power MOSFETs (Metal-oxide-semiconductor field-effect transistor) that are specifically designed for high performance and fast switching applications. These devices are offered in a robust SOT-223 package, and their specifications include low gate charge and low gate-resistance for improved speed and efficiency, along with low on-resistance for lower power dissipation. The series is available with either an N-channel or P-channel polarity, enabling a wide range of applications in low voltage switching systems.
