K3569 transistor


This is 600V, 10A, Silicon N Channel MOS Type Field Effect Transistor.

It is high voltage and current ratings, which make it suitable for use in high-power applications such as motor control, power supplies, and lighting systems. It also has a low on-state resistance, which results in low power dissipation and improved efficiency.

This is relatively high gate charge, which may limit its switching speed in some applications. Additionally, like all MOSFETs, the K3569 is sensitive to electrostatic discharge (ESD) and may require additional protection circuitry to prevent damage during handling.


1.  Low drain-source ON resistance: RDS (ON)= 0.54Ω(typ.)

2.  High forward transfer admittance: |Yfs| = 8.5S (typ.)

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

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