A3120-500E 2.0A 输出电流 IGBT 门驱动光电耦合器
HCPL-3120 门驱动光电耦合器内含 GaAsP LED,通过光学耦合到带有功率级输出的集成电路,这些光电耦合器非常适合用来驱动电机控制变频应用中的功率 IGBT 和 MOSFET,输出级的高工作电压范围提供了门控器件所需的驱动电压。
这些光电耦合器提供的电压和电流非常适合用来直接推动规格达到 1,200V/100A 的 IGBT,对于规格较高的 IGBT,可以使用 HCPL-3120 系列来推动 IGBT 门驱动分立功率级电路,ACNW3190 拥有 VDE 0844 中 VIORM = 630Vpeak 的绝缘电压。
