  • The ACS120 belongs to the AC line switch family. This high performance switch circuit is able to control a load of up to 2 A.

    The ACS™ switch embeds a high voltage clamping structure to absorb the inductive turn off energy and a gate level shifter driver to separate the digital controller from the main switch. It is triggered with a negative gate current flowing out of the gate pin.

    Key Features

    • Blocking voltage: VDRM/ VRRM= +/- 700 V
    • Avalanche controlled: VCLtyp. = 1100 V
    • Nominal conducting current: IT(RMS)= 2 A
    • Gate triggering current: IGT< 10 mA
    • High noise immunity: static dV/dt > 500 V/μs
