Switching Regulator Applications
• Low drain-source ON-resistance: RDS (ON) = 0.43 Ω (typ.)
• High forward transfer admittance: ⎪Yfs⎪ = 5.5 S (typ.)
• Low leakage current: IDSS = 10 μA (max) (VDS = 450 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).
