Switching Regulator Applications
Unit: mm
• Small gate charge: Q_g = 60 nC (typ.)
• Low drain-source ON resistance: R_{DS (ON)} = 0.22 Ω (typ.)
• High forward transfer admittance: |Y_fs| = 11 S (typ.)
• Low leakage current: I_DSS = 500 μA (V_DS = 600 V)
• Enhancement model: V_th = 2.0 to 4.0 V (V_DS = 10 V, I_D = 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).
