TOSHIBA Field Effect Transistor Silicon N Channel MOS Type (U-MOSII)
2SK3440
Switching Regulator, DC-DC Converter Applications
Motor Drive Applications
• Low drain-source ON resistance: RDS (ON) = 6.5 mΩ (typ.)
• High forward transfer admittance: |Yfs| = 30 S (typ.)
• Low leakage current: IDSS = 100 μA (VDS = 60 V)
• Enhancement mode: Vth = 2.0 to 4.0 V (VDS = 10 V, ID = 1 mA)

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate
reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/Derating Concept and
Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
