通过缓冲电路降低开关噪声（低尖峰技术）
东芝不断改进各种性能，以提高应用设备的效率，减少MOSFET发热。在第8代MOSFET（U-MOSⅧ-H系列）中，除了这些改进外，还采用了新的单元结构，以降低开关过程中的噪声和振铃。此外，如下图所示，第9代U-MOSⅨ-H系列提供一系列低尖峰型和高效型产品，前者具有优化的缓冲电路常数。
开关波形比较（VDSS＝60V型）
R负载开关波形
VDD＝30V，ID＝50A
RG＝4.7Ω，RGS＝4.7Ω
电阻负载
Ta＝25℃
L负载开关波形（trr）
VDD＝30V
IDR＝25A
di/dt=220A/μs
感性负载
Ta＝25℃
东芝的TPH1R306P1是U-MOSⅨ-H系列追求高效率的低尖峰低噪声产品。与传统的TPH1R306PL比较，对于R负载开关波形，VDS的尖峰噪声减小约13%，对于L负载开关波形(（Trr），VDS的尖峰噪声减小约为35%。
