Product Overview
The 2SK3018 is an N-channel enhancement-mode MOSFET designed for low-current switching, signal control, and compact interface applications. It features a 30V drain-source voltage rating, 100mA continuous drain current, and a maximum drain-source on-resistance of 7.5Ω at a 10V gate drive. Its low input capacitance and small package make it suitable for low-power switching and signal-processing circuits.
Packaged in a SOT-23 surface-mount package, the 2SK3018 is well suited to space-constrained PCB designs. It can be used in digital logic interfaces, signal gating, low-current load switching, and general-purpose MOSFET control applications.
