* Since temperature rise of this product are affected by the circuit board size, materials, peripheral heat-producing components, etc.
check that the solder fillet part temperature after mounting is less than the solder melting point (180°C) in operating condition and that
the package surface is 200°C or less. Also, please install radiating patterns and carefully design the pattern width with respect to the
load current so that the above temperatures can be maintained.
