  • The ACST6 series belongs to the ACS/ACST power switch family built with A.S.D. (application specific discrete) technology. This high performance device is suited to home appliances or industrial systems, and drives loads up to 6 A.

    This ACST6 switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standards. The ACST610 needs only low gate current to be activated (IGT < 10 mA) and still shows a high noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).

    Key Features

    • Triac with overvoltage protection
    • Low IGT (< 10 mA)
    • TO-220FPAB insulated package:
      • complies with UL standards (file ref: E81734)
      • insulation voltage: 2000 VRMS
