Notes
1. When operating at VP > 16 V, the output power must be limited to 85 W at THD = 10% (or minimum load is 6 Ω).
2. Tj is a theoretical temperature which is based on a simplified representation of the thermal behaviour of the device.
Tj = Tc + P × Rth(j-c), where Rth(j-c) is a fixed value to be used for the calculation of Tj. The rating for Tj limits the
allowable combinations of power dissipation P and case temperature Tc (in accordance with IEC 60747-1).
