WebIt can be noted that in figure 6 the dV/dt and tail current losses are around the same with a gate resistance of 47 Ω. Even though the tail current is constant, the losses in a system are often predominantly due to dV/dt, because the value of the gate resistance is often too high. In the example of figure 7, the total losses per WebJST16A-600BW 数据表, JST16A-600BW datasheets, JST16A-600BW pdf, JST16A-600BW 集成电路 : JIEJIE - With high ability to withstand the shock loading of large current, JST16 series triacs provide high dv/dt rate ,alldatasheet, 数据表, 电子元件和半导体, 集成电路, 二极管, 三端双向可控硅 和其他半导体的
