9 / 19 page STA518 Electrical specifications 9/19 Considering that for the STA518 the Thermal resistance Junction to slug is 1.5°C/W and the extimated Thermal resistance due to the grease placed between slug and heat sink is 2.3°C/W ( the use of thermal pads for this package is not recommended), the suitable Heat Sink Rth to be used can be drawn from the following graph Figure 11, where is shown the Derating Power vs.Tambient for different heatsinkers. 3.5 Electrical characteristcs Table 6. Electrical Characteristcs Refer to circuit in Figure 3 (VL = 3.3V; VCC = 30V; RL = 8Ω; fsw = 384KHz; Tamb = 25°C unless otherwise specified) Symbol Parameter Test conditions Min. Typ. Max.
