Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in JEDEC temperature, etc.) may cause this product to decrease in the JEITA reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the TOSHIBA 2-3S1A absolute maximum ratings. Weight: 10 mg (typ.) 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 an FR4 board. 2 (25.4 mm x 25.4 mm x 1.6 t, Cu Pad: 645 mm )

Notice on Usage
Vth can be expressed as the voltage between gate and source when the low operating current value is ID = 1 mA for this product. For normal switching operation, VGS (on) requires a higher voltage than Vth and VGS (off) requires a lower voltage than Vth. (The relationship can be established as follows: VGS (off) < Vth < VGS (on).) Take this into consideration when using the device.
Handling Precaution
When handling individual devices that are not yet mounted on a circuit board, make sure that the environment is protected against electrostatic discharge. Operators should wear antistatic clothing, and containers and other objects that come into direct contact with devices should be made of antistatic materials.
