K3451 mosfet


The K3451 is a N-channel power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by Fuji. It is commonly used as a switch in power electronics applications, where its low on-resistance and fast switching speed make it well-suited for high-efficiency power conversion systems.

The 2SK3451 has a maximum drain-source voltage of 600V and a maximum drain current of 13A,
making it suitable for high voltage, high current applications.


1. High speed switching

2. Low on-resistance

3. No secondary breadown

4. Low driving power

5. Avalanche-proof
