2SK3743
TOSHIBA Field Effect Transistor Silicon N Channel MOS Type (π-MOSV)
2SK3743
Switching Regulator Applications
Unit: mm
• Low drain-source ON resistance: RDS (ON) = 0.29 Ω (typ.)
• High forward transfer admittance: |Yfs| = 5.8 S (typ.)
• Low leakage current: IDSS = 100 μA (max) (VDSS = 450 V)
• Enhancement-mode: Vth = 3.0 to 5.0 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).
