PARAMETER

TAS5613PHD

TAS5613DKD

RθJC (°C/W) – 2 BTL or 4 SE channels

3.2

2.1

RθJC (°C/W) – 1 BTL or 2 SE channel(s)

5.4

3.5

RθJC (°C/W) – 1 SE channel

Pad Area (2)

64 mm2

80 mm2

(1)

JC is junction-to-case, CH is case-to-heat sink

(2)

RθH is an important consideration. Assume a 2-mil thickness of typical thermal grease between the pad area and the heat sink and both

channels active. The RθCH with this condition is 1.22°C/W for the PHD package and 1.02°C/W for the DKD package.
