By use of the method, the low-breakdown and breakover position of great majority plane transistor core can be eliminated to increase the qualification rate of the tube core, especially the powerful transistor. 采用该技术可消除绝大多数平面晶体管管芯的低击穿和穿通点,从而大幅度提高管芯、特别是大功率管管芯的合格率和高档品率。
Theory and experiments show that, by controlling the diameter and the depth of the well, the breakover voltage of the overvoltage self-protection thyristor can be controlled. 理论和实验均表明,控制门极的穴径和穴深可以达到控制门极自保护特性的目的。
Selection and design of method for breakover test of locomotive control console and electrical cabinet 机车操纵台、电器柜导通试验方法的选择及设计
In resonance conditions. voltage outputs of the vibration structures are up to 0. 4V, which can breakover double germanium diode adequately in rectification circuit. 该结构在共振条件下将运动信号转换为电压信号输出时,电压可达0.4V以上,足以开启双锗二极管进行电路整流。
