STMicroelectronics ACST2
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.| Part No. | ACST2 |

FEATURES
● Triac with overvoltage crowbar technology● High noise immunity: static dV/dt > 500 V/μs
● TO-220FPAB insulated package: – complies with UL standards (File ref : E81734) – insulation voltage: 2000 VRMS
● 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 – Interfaces directly with the micro-controller – High immunity against fast transients described in IEC 61000-4-4 standards
APPLICATIONS
● AC mains static switching in appliance and industrial control systems● Driving low power highly inductive loads like solenoid, pump, fan, and micro- motor
DESCRIPTION
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).
