Product overview

Description

The ACST12 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 12 A.

This ACST12 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 standard. The ACST1210-7 needs a low gate current to be activated (IGT< 10 mA) and still provides a high electrical noise immunity complying with the IEC 61000-4-4 standard. The ACST1235-7 offers an extremely high static dV/dt immunity of 2 kV/μs minimum.

  • All features

    • Triac with overvoltage crowbar technology
    • Low IGT(<10 mA) or high immunity(IGT<35 mA) version
    • High noise immunity: static dV/dt > 2000 V/μs
    • Benefits
      • Enables equipment to meet IEC 61000-4-5
      • High off-state reliability with planar technology
      • Need no external over voltage protection
      • Reduces the power passive component count
      • High immunity against fast transients described in IEC 61000-4-4 standards
