Features and Applications

The ACST4 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 4 A.

This ACST4 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 ACST410 needs only a 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).


  • Triac with overvoltage protection
  • Low IGT (<10 mA) or high immunity (IGT<35 mA) version
  • High noise immunity: static dV/dt > 1000 V/µs
  • TO-220FPAB insulated package: 1500 V rms
  • Benefits
    • Enables equipment to meet IEC 61000-4-5
    • High off-state reliability with planar technology
    • Needs no external overvoltage protection
    • Reduces the power passive component count
    • High immunity against fast transients described in IEC 61000-4-4 standards
