2SK3842
TOSHIBA Field Effect Transistor Silicon N Channel MOS Type (U-MOSIII)
2SK3842
Switching Regulator Applications, DC-DC Converter and
Motor Drive Applications
Unit: mm
• Low drain-source ON resistance: RDS (ON) =4.6 mΩ (typ.)
• High forward transfer admittance: |Yfs| = 93 S (typ.)
• Low leakage current: IDSS = 100 μA (max) (VDS = 60 V)
• Enhancement model: 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).

Note 1: Ensure that the channel temperature does not exceed 150℃.
Note 2: VDD = 25 V, Tch = 25°C (initial), L = 78 μH, RG = 25 Ω, IAR = 75 A
Note 3: Repetitive rating: pulse width limited by maximum channel
temperature
This transistor is an electrostatic-sensitive device. Please handle with
caution.
Notice:
Please use the S1 pin for gate
input signal return. Make
sure that the main current
flows into S2 pin.
