The K15A50D is 500V, 15A, 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) = 0.24 Ω (typ.)

2. High forward transfer admittance: |Yfs| = 7.0 S (typ.)

3. Low leakage current: IDSS = 10 μA (VDS = 500 V)

4. Enhancement mode: Vth = 2.0 to 4.0 V (VDS = 10 V, ID = 1 mA)
