PACKAGE HEAT DISSIPATION RATINGS (1) PARAMETER TAS5611APHD TAS5611ADKD RqJC (°C/W) – 2 BTL or 4 SE channels 3.2 2.1 RqJC (°C/W) – 1 BTL or 2 SE channel(s) 5.4 3.5 RqJC (°C/W) – 1 SE channel 7.9 5.1 Pad Area (2) 64 mm2 80 mm2 (1) JC is junction-to-case, CH is case-to-heat sink (2) RqCH is an important consideration. Assume a 2-mil thickness of thermal grease with a thermal conductivity of 2.5 W/mK between the pad area and the heat sink and both channels active. The RqCH with this condition is 1.1°C/W for the PHD package and 0.44°C/W for the DKD package. Table 1.
