K20A60U transistor mosfet


K20A60U is 600V, 20A, Silicon N Channel MOS Type Transistor(Metal Oxide Semiconductor Field Effect Transistor).

This 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) = 0.165 Ω (typ.)

2. High forward transfer admittance: ⎪Yfs⎪ = 12 S (typ.)

3. Low leakage current: IDSS = 100 μA (max) (VDS = 600 V)

4. Enhancement-mode: Vth = 3.0 to 5.0 V (VDS = 10 V, ID = 1 mA)
