DSOP Advance，热增强的双面散热封装，提高了大电流应用的电源效率
DSOP Advance在封装的顶部有一个金属板（E-Pad），用于芯片散热。这种金属板改进了散热，将减少高电流导通期间MOSFET温度的增加，有助于提高电源电路的功率密度和效率。与相同封装尺寸的SOP Advance相比，DSOP Advance的热阻Rth(ch-c)降低了45%。由于DSOP Advance的封装样式与传统的SOP Advance相同，因此可以在不改变印刷电路板布局的情况下进行替换。
用TPWR8503NL代替东芝的30V MOSFET TPHR9003NL可降低MOSFET温度10.3°C。当安装散热片时，器件温度最大降低26℃。
模拟散热结果（SOP Advance vs. DSOP Advance）
下图显示了SOP Advance和DSOP Advance的模拟散热比较结果。上部为散热条件的侧视图，下部为散热条件的俯视图。双面散热式DSOP Advance比单面散热式SOP Advance降低MOSFET温度约40%。
