ACST4:Overvoltage protected AC switch

The ACST4 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 4 A.

This ACST4 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 ACST410 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).

Provides UL 1557 certified insulation rated at 2000 V rms.

Key Features

  • 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 complies with UL 1557 standard (file ref: E81734)
  • 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
