  • The ACST2 series belongs to the ACS/ACST power switch family. This high performance device is suited to home appliances or industrial systems and drives loads up to 2 A.

    This ACST2 switch embeds a Triac structure with a high voltage clamping device to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standards. The component needs a low gate current to be activated (IGT < 10 mA) and still shows a high electrical noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).

    Key Features

    • Triac with overvoltage crowbar technology
    • High noise immunity: static dV/dt > 500 V/μs
    • TO-220FPAB insulated package:
      • complies with UL standards (File ref: E81734)
      • Insulation voltage : 2000 VRMS
