K2401 is Silicon N Channel MOS Type Field Effect Transistor.

An N-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of field effect transistor (FET) that uses an N-type semiconductor material as the conducting channel to control the flow of current.

When a positive voltage is applied to the gate terminal, it attracts electrons to the channel, creating an inversion layer and allowing current to flow between the source and drain terminals.

N-channel MOSFETs are widely used in a variety of electronic applications due to their high input impedance, fast switching speeds, and low power consumption. They are commonly used as switches, amplifiers, and voltage regulators.


1. Low drain−source ON resistance : RDS (ON) = 0.13 Ω (typ.)

2. High forward transfer admittance : |Yfs| = 17 S (typ.)

3. Low leakage current : IDSS = 100 μA (max) (VDS = 200 V)

4. Enhancement mode : Vth = 1.5~3.5 V (VDS = 10 V, ID = 1 mA)
