the power dissipated in the circuit must be re- moved by adding an external heatsink. thanks to the multiwatt package attaching the heatsink is very simple, a screw or a compres- sion spring (clip) being sufficient. between the heatsink and the package it is better to insert a layer of silicon grease, to optimize the thermal contact ; no electrical isolation is needed between the two mounting instructions figure 18 : maximum allowable power dissipa- tion versus ambient temperature figure 19 : output power versus case temperature figure 20 : output power and drain current ver- sus case temperature tda2009a 10/12
