As shown in Figure 12, the amount of copper area to which the SOP-8 (Exposed Pad) is mounted affects thermal
performance. When mounted to the standard SOP-8 (Exposed Pad) pad of 2 oz. copper (Figure 12.a),
θ
JA
is 86
°
C/W.
Adding copper area of pad under the SOP-8 (Exposed Pad) (Figure 12.b) reduces the
θ
JA
to 73
°
C/W. Even further,
increasing the copper area of pad to 70mm
2
(Figure 12.d) reduces the
θ
JA
to 65
°
C/W.
