2SK3742
TOSHIBA Field Effect Transistor Silicon N-Channel MOS Type (π-MOSIV)
www.DataSheet4U.com
2SK3742
Switching Regulator Applications
• Low drain-source ON resistance: RDS (ON) = 2.2 Ω (typ.)
• High forward transfer admittance: |Yfs| = 3.5 S (typ.)
• Low leakage current: IDSS = 100 μA (VDS = 720 V)
• Enhancement model: Vth = 4.0~5.0 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).

Note 1: Ensure that the channel temperature does not exceed 150°C during use of the device.
Note 2: VDD = 90 V, Tch = 25°C (initial), L = 43.6 mH, IAR = 5.0 A, RG = 25 Ω
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
This transistor is an electrostatic-sensitive device. Handle with care.
