STMicroelectronics ACST4
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.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 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 – High immunity against fast transients described in IEC 61000-4-4 standards
APPLICATIONS
● AC mains static switching in appliance and industrial control systems● Drive of medium power AC loads such as: – Universal drum motor of washing machine – Compressor of fridge or air conditioner
DESCRIPTION
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).
