Note 1:

Thermal Resistance is specified with approximately 1 square of 1 oz cooper.

Note 2:

Absolute Maximum ratings are threshold limit values that must not be exceeded even for an

instant under any conditions. Moreover, such values for any two items must not be reached

simultaneously. Operation above these absolute maximum ratings may cause degradation

or permanent damage to the device. These are stress ratings only and do not necessarily

imply functional operation below these limits.

Note 3:

TJ is calculated from the ambient temperature TA and power dissipation PD according to the

following formula: TJ = TA + (PD) × (220°C/W)
