2SK2838
TOSHIBA Field Effect Transistor Silicon N Channel MOS Type (π−MOSV)
2SK2838
Chopper Regulator, DC−DC Converter and Motor Drive
Applications
Unit: mm
z Low drain−source ON resistance : RDS (ON) = 0.84 Ω (typ.)
z High forward transfer admittance : |Yfs| = 4.4 S (typ.)
z Low leakage current : IDSS = 100 μA (max) (VDS = 400 V)
z 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).
