Unit: mm
• Low drain-source ON resistance: R_{DS (ON)} = 6.5 mΩ (typ.)
• High forward transfer admittance: |Y_fs| = 30 S (typ.)
• Low leakage current: I_DSS = 100 μA (V_DS = 60 V)
• Enhancement mode: 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).

Notice:
Please use the S1 pin for gate input
signal return. Make sure that the
main current flows into the S2 pin.
Note 1: Ensure that the channel temperature does not exceed 150°C.
