Alpha and Omega Semiconductor now offers five power MOSFETs in rugged LFPAK 5×6-mm surface-mount packages. The low-profile, flat power package minimizes vertical PCB space and performs reliably in harsh environments. MOSFETs in the 4-lead LFPAK are available in 40-V, 60-V, and 100-V variants.

LFPAK packaging enhances board-level reliability with features such as gull-wing leads and a larger copper clip. The gull-wing leads offer durability against board-level environmental stresses and facilitate optical inspection during PCB manufacturing. The larger clip improves current handling, reduces on-resistance, and provides better heat dispersion compared to wire bonding, while also minimizing parasitic inductance.
LFPAK MOSFETs are well-suited for applications requiring high reliability, including those in the industrial, server power, telecommunications, and solar sectors. The table below highlights the key specifications of the five available devices:
