Sales Briefcase
  • The ACS108-8SUN belongs to the AC line switch range (built with A.S.D.®technology).This high performance switch can control a load of up to 0.8 A.

    The ACS108-8SUN switch includes an overvoltage crowbar structure to absorb the overvoltage 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

    • Less footprint area than SOT-223 (saves PCB)
    • ECOPACK®2 compliant component
    • Thinner option versus SOT-223 (1.1 mm max. thickness)
    • Enables equipment to meet IEC 61000-4-5
    • High noise immunity against static dV/dt and IEC 61000-4-4 burst
    • Overvoltage protection by crowbar technology
    • Needs no external protection snubber or varistor
    • Reduces component count by up to 80% and Interfaces directly with the micro-controller
    • VCLgives headroom before clamping then crowbar action
    • Common package tab connection supports connection of several alternating current switches on the same cooling pad
