The maximum allowable power dissipation depends upon the thermal resistance junction-ambient. Figure 8 shows the dissipable power as a function of ambient temperature for different heatsink thermal resistance. 2-the heatsink can have a smaller factor of safety compared with that of a conventional SHORT CIRCUIT (AC CONDITIONS) circuit. There is no device damage in the case The TDA7263 can withstand accidental short cir- of excessive.
