  • The ACST8 series belongs to the ACS/ACST power switch family built around A.S.D. (application specific discrete) technology. This high performance device is suited to home appliances or industrial systems and drives an induction motor up to 8 A.

    This ACST8 device 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.
    ACST8 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
    • High noise immunity: static dV/dt > 2000 V/μs
    • TO-220FPAB insulated package:
      • complies with UL standards (file ref: E81734)
      • insulation voltage: 2000 VRMS
