ACST2:Overvoltage protected AC switch

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
  • ACST210-8FP, in the TO-220FPAB package, provides insulation voltage rated at 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 component count
    • Interfaces directly with the micro-controller
    • High immunity against fast transients described in IEC 61000-4-4 standards
