Motor Drive Applications
• 4-V gate drive
• Low drain-source ON-resistance: R_{DS (ON)} = 1.2 Ω (typ.)
• High forward transfer admittance: |Y_fs| = 2.2 S (typ.)
• Low leakage current: I_DSS = 100 μA (max) (V_DS = 250 V)
• Enhancement mode: V_th = 1.5 to 3.5 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).

Note 1: Ensure that the channel temperature does not exceed 150°C.
Note 2: V_DD = 50 V, T_ch = 25°C, L = 6.7 mH, I_AR = 3 A, R_G = 25 Ω
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
This transistor is an electrostatic-sensitive device. Handle with care.
