The NTK3134N from ON Semiconductor is a high-performance, single N-Channel MOSFET designed for power and interface switching applications in ultra-small portable electronics. Packaged in a compact SOT-723 form factor, which is 44% smaller in footprint and 38% thinner than the SC89, this MOSFET features a low RDS(on) for efficient load switching. It operates at low logic level gate drives, with a maximum drain-to-source voltage (VDSS) of 20V and a continuous drain current (ID) of up to 890mA at 25°C. The component supports pulsed drain currents up to 1.8A and boasts ESD protection. The NTK3134N is also Pb-Free, Halogen Free/BFR Free, and RoHS Compliant, making it an environmentally friendly choice for designers. Key applications include load/power switching, interface switching, logic level shifting, and battery management.
