<p><span>近日，</span><span>电动摩托车、电动叉车与其他轻型电动车（</span><span>LEV</span><span>）以及电动手工具和电池管理系统等应用皆需要高额定电流、坚固耐用与更长的使用寿命等要求。英飞凌科技股份有限公司</span><span><span> </span>(FSE</span><span>：</span><span>IFX/OTCQX</span><span>：</span><span>IFNNY</span><span>)通过为电源系统设计人员提供更多选择，以符合其不同的设计需求，并在最小空间内展现最高性能。英飞凌借助创新的</span><span>TO-Leadless</span><span>（</span><span>TOLL</span><span>）封装，在</span><span>OptiMOS™</span><span>功率</span><span>MOSFET TOLx</span><span>系列推出两款新封装：</span><span>TOLG</span><span>（配备鸥翼型导线的</span><span>TO</span><span>导线）以及</span><span><span> </span>TOLT</span><span>（</span><span>TO</span><span>导线顶部散热）。</span><span>TOLx</span><span>系列皆具备极低的</span><span>R </span><span>DS(on)</span><span> </span><span>与超过</span><span>300 A</span><span>的高额定电流，可提升高功率密度设计的系统效率。</span></p>
<p><span>TOLG</span><span>封装结合了</span><span>TOLL</span><span>与</span><span>D </span><span>2</span><span>PAK 7</span><span>针脚封装的最佳功能，与</span><span>TOLL</span><span>共用相同的</span><span>10 x 11</span><span><span> </span></span><span>mm </span><span>2</span><span>基底面与电气性能，并增加了与</span><span>D </span><span>2</span><span>PAK 7</span><span>针脚相容的弹性。</span><span>TOLG</span><span>的主要优势在採用铝绝缘金属基板（</span><span>Al-IMS</span><span>）的设计时特别明显。在这些设计中，热扩张係数（</span><span>CTE</span><span>）说明材料在温度变化时的形状变化趋势，比铜</span><span>IMS</span><span>和</span><span>FR4</span><span>电路板更高。</span></p>
<p><span>随著时间流逝，电路板上的温度循环（</span><span>TCoB</span><span>）会造成封装和</span><span>PCB</span><span>之间的焊接点出现裂缝。通过鸥翼型导线的灵活性，</span><span>TOLG</span><span>展现出色的焊接点耐用性，在反覆发生温度循环的应用中大幅增加了产品的可靠性。与</span><span>IPC-9701</span><span>标准要求相比，全新封装能够展现两倍的</span><span>TCoB</span><span>性能。</span></p>
<p><span>TOLT</span><span>封装针对优异的热性能进行优化。此封装在结构方面采用上下翻转的导线，将裸露的金属置于顶端，且每一面都有多条鸥翼型导线，可提供高电流承载的漏极与源极连接。在导线上下翻转的框架中，热量会从裸露的金属顶端穿过绝缘材料，直接传到散热片。与</span><span>TOLL</span><span>底部冷却封装相比，</span><span>TOLT</span><span>的</span><span> R </span><span>thJA</span><span>改善了</span><span>20%</span><span>，</span><span>R </span><span>thJC</span><span>则改善了</span><span>50%</span><span>。这些规格可降低系统物料成本，特别是散热片。此外，由于现在可将组件安装在</span><span>MOSFET</span><span>的底部，因此采用</span><span>TOLT</span><span>封装的</span><span>OptiMOS</span><span>能够减少</span><span>PCB</span><span>空间。</span></p>
