Switching Regulator Applications
• Low drain-source ON-resistance: RDS (ON) = 2.0 Ω(typ.)
• High forward transfer admittance: |Yfs| = 1.8 S (typ.)
• Low leakage current: IDSS = 10 μA (max) (VDS = 550 V)
• Enhancement mode: Vth = 2.4 to 4.4 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).
