Switching Regulators and DC-DC Converter Applications
Motor Drive Applications
Low drain-source ON-resistance: RDS (ON) = 0.8 Ω (typ.)
High forward transfer admittance: |Yfs| = 4.5 S (typ.)
Low leakage current: IDSS = 100 μA (max) (VDS = 250 V)
Enhancement mode: Vth = 1.5 to 3.5 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).

Note 1: Ensure that the channel temperature does not exceed 150°C.
Note 2: VDD = 50 V, Tch = 25°C (initial), L = 4.28 mH, RG = 25 Ω, IAR = 4.5 A
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
This transistor is an electrostatic-sensitive device. Handle with care.
