Switching Regulator Applications
• Low drain-source ON-resistance: RDS (ON) = 1.1 Ω (typ.)
• High forward transfer admittance: |Yfs| = 5.0S (typ.)
• Low leakage current: IDSS = 100 μA (VDS = 600 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).
