THERMAL AND MECHANICAL RATINGS
ABSOLUTE MAXIMUM CURRENT RATINGS
Stresses above those listed under 'Absolute Maximum Ratings' may cause permanent damage to the device. In extreme
conditions, as with all semiconductors, this may include potentially hazardous rupture of the package. Appropriate safety
precautions should always be followed. Exposure to Absolute Maximum Ratings may affect device reliability.

Note: The data given in this datasheet with regard to forward voltage drop is for calculation of the power dissipation in the
semiconductor elements only. Forward voltage drops measured at the power terminals of the module will be in excess of these
figures due to the impedance of the busbar from the terminal to the semiconductor.
