ACST4 Datasheet 4 A - 800 V overvoltage protected AC switch OUT COM G DPAK TO-220FPAB G OUT COM OUT G COM Product status link ACST4 Product summary IT(RMS) 4A VDRM/VRRM 800 V IGT (ACST410) 10 mA IGT (ACST435) 35 mA 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 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...
