NCE4688 60V 6.3A Dual Channel Power MOSFET SOP-8

NCE4688 60V 6.3A Dual Channel Power MOSFET SOP-8 delivers high-efficiency switching and power management in a compact surface-mount package, integrating two N-Channel enhancement mode MOSFETs into a single SOP-8 footprint. This dual-channel design allows engineers to implement H-bridge motor drivers, synchronous buck converters, or advanced battery protection circuits with maximum component density. Consequently, the NCE4688 significantly reduces PCB area and assembly complexity in space-constrained applications. We manufacture this Power MOSFET with advanced trench technology, achieving an extremely low on-state resistance (R_DS(ON)), which minimizes power loss and improves overall thermal performance. Therefore, you should select the NCE4688 when your design demands a reliable, high-current, and thermally efficient solution for low-voltage switching tasks.
