  • Q相比DPAK，LFPAK既然优势明显，那么成为市场主流封装，主要障碍在哪？

    Athe key bottle neck is the price

  • Q什么是DPAK，DPAK与LFPAK有什么区别？

    AThe major difference is the LFPAK designed the big thermal pad in buttom side , it will get better thermal performacne comare with DPAK

  • QLFPAK是目前最完美的封装形式吗？

    Ayes

  • QLFPAK封装尺寸为？

    A5x6x1 mm

  • QLFPAK封装有哪些特点？

    ALFPAK pins allow for thermal expansion due to temperature difference between the MOSFET & PCB and also mechanical strain due to PCB bending & flexing

  • QLFPAK封装如何在缩小空间的同时维持相同功耗？

    ALFPAK offerf the big buttom side thermal pad to dissipate the heat to achieve the better thermal performance.

  • Q请问LFPAK的热性能怎么样?和DPAK封装相比谁更好？

    AThe LFPAK provide the good thermal perfomance compare with DPAK and LFPAK offer the smaller dimension

  • Q请问LFPAK封装如何减少开关损耗的？

    ADue to the bottum side thermal pad , the heat could via the pad dissipate to the PCB.

  • QLFPAK除了比QFN更可靠外，还有哪些优势？

    AThe LFPAK is more robust for some stress ,it is qualified by IECQ101 ( Auotmotive )

  • Q能否完全替代DPAK封装？

    AFor package poower dissipation perfromance point of view , we set the target to replace the DPAK

  • QLFPAK封装的散热性能如何?

    ASince the LFPAK designed the big thermal pad in buttom side , it provide the better thermal performance compare with the standard lead package.

  • QLFPAK是NXP独家封装技术吗？

    AYES

  • QLFPAK MOSFET比DPAK实际小了多少？

    A25% reduce

  • Q与SO-8封装是否通用？

    AIt could be co-layout with SO-8 package
