2SK1544

The 2SK1544 is a kind of field effect transistor. It is silicon N channel MOS type. The device is designed for high speed, high current switching applications as well as DC-DC converter and motor drive applications. There are some features as follows: (1)low drain-source ON resistance: RDS(ON)=0.15 (typ); (2)high forward transfer admittance: |Yfs|=21 S (typ); (3)low leakage current: IDSS=300A (max) (VDS=500 V); (4)enhancement-mode: Vth=1.5 to 3.5 V (VDS=10 V, ID=1 mA).
