The 2SK1398 is N-channel MOS Field Effect Transistor designed for a high-speed switching device in digital circuits. The 2SK1398 is driven a 2.5-V power source, it is suitable for applications including headphone stereos which need power saving.
Directly driven by ICs having a 3-V power supply. Not necessary to consider driving current because of its high input impedance. Possible to reduce the number of parts by omitting the bias resistor. Can be used complementary with the 2SJ184.
