Low drain-source ON-resistance: RDS (ON) = 4.2 m(typ.)
High forward transfer admittance: |Yfs| = 110 S (typ.)
Low leakage current: IDSS = 100 μA (VDS = 60 V)
Enhancement mode: Vth = 1.5 to 2.5 V (VDS = 10 V, ID = 1 mA)

Note 1: Ensure that the channel temperature does not exceed 150°C.
Note 2: VDD = 25 V, Tch = 25°C (initial), L = 78 μH, RG = 25 Ω, IAR = 75 A
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
Note 4: 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).
This transistor is an electrostatic-sensitive device. Handle with care.

Note: Use the S1 pin to return the gate
signal to source. Board traces should
be designed so the main current flows
to the S2 pin.
