High Speed Switching Applications
Unit: mm
• Small Package
• Low ON-resistance: R_on = 39 mΩ (max) (@V_GS = 10 V)
: R_on = 57 mΩ (max) (@V_GS = 4.5 V)
• High speed: t_on = 24 ns (typ.)
: t_off = 19 ns (typ.)

temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.
Weight: 10 mg (typ.)
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: Mounted on FR4 board
(25.4 mm × 25.4 mm × 1.6 t, Cu pad: 645 mm²)
Note 2: The pulse width limited by max channel temperature.

Handling Precaution
When handling individual devices (which are not yet mounted on a circuit board), be sure that the
environment is protected against electrostatic electricity. Operators should wear anti-static clothing, and
containers and other objects that come into direct contact with devices should be made of anti-static materials.
The Channel-to-Ambient thermal resistance R_{th (ch-a)} and the drain power dissipation P_D vary according to
the board material, board area, board thickness and pad area, and are also affected by the environment in
which the product is used. When using this device, please take heat dissipation fully into account.
