  • The ACST1635-8FP belongs to the AC power switch range built with A.S.D.®technology. This high performance device is designed for home appliances or industrial systems and drives loads up to 16 A.

    This ACST1635-8FP switch embeds a Triac structure with a high voltage crowbar device to absorb the inductive turn-off energy and withstand line surges such as those described in the IEC 61000-4-5 (surge immunity test).

    Key Features

    • Enables equipment to meet IEC 61000-4-5 surge with overvoltage crowbar technology
    • High noise immunity against static dV/dt and IEC 61000-4-4 burst
    • High junction temperature: Tj= 150 °C
    • Needs no external over-voltage protection
    • VCLgives headroom before clamping then crowbar action
    • Reduces component count
    • ECOPACK®2 compliant component
    • Complies with UL standards (File ref: E81734)
    • Provides UL certified insulation rated at 2000 V rms
