厄利电压是一个重要的参数,它定义为在MOSFET的输出特性曲线(I-V curve)上,当集电极电流(drain current)达到其最大值一半时的集电极-源极电压(Vds)。这个定义是在长沟道MOSFET的情况下提出的,对于短沟道和超短沟道器件,这个定义可能需要做一些调整。 厄利电压的物理意义在于,它反映了MOSFET在饱和区的行为,即当...
1. 转移特性曲线(Transfer Characteristic Curve) 定义与描述:转移特性曲线展示了栅源电压(V_GS)对漏极电流(I_D)的控制作用,通常是在固定漏源电压(V_DS)条件下测量的。该曲线反映了MOS管的开关行为以及其在不同栅压下导电能力的变化。 关键点分析: 阈值电压(V_TH):这是使MOS管开始导通的栅源电压值。在V_...
这就单纯是PN结雪崩击穿了(avalanche Breakdown),主要是漏极反偏电压下使得PN结耗尽区展宽,则反偏电场加在了PN结反偏上面,使得电子加速撞击晶格产生新的电子空穴对 (Electron-Hole pair),然后电子继续撞击,如此雪崩倍增下去导致击穿,所以这种击穿的电流几乎快速增大,I-V curve几乎垂直上去,很容烧毁的。(这点和源漏穿...

It is established that considerable dispersion of the insulator thickness modifies the I-V curve shape. Values of the current dispersion are determined in a broad range of linear dimensions of the MOS device. The modeling has been performed using the most recent data on the parameters of ...
At the low output power range, the switching losses dominate the efficiency curve. The OptiMOS™ 6 power MOSFET BSC010N04LS6 achieves a much better efficiency in this range compared to the same RDS(on) OptiMOS™ 5 due to its superior switching performance. Moreover, at a...
