ACST6 Overvoltage protected AC switch Datasheet - production data Benefits OUT Enables equipment to meet IEC 61000-4-5 High off-state reliability with planar technology Needs no external overvoltage protection G Reduces the power passive component count G OUT OUT COM High immunity against fast transients COM described in IEC 61000-4-4 standards TO-220AB TO-220FPAB ACST610-8T ACST610-8FP Applications OUT OUT AC mains static switching in appliance and industrial control systems Drive of medium power AC loads such as: G G OUT Universal motor of washing machine drum COM COM Compressor for fridge or air conditioner DPAK IPAK ACST610-8G ACST610-8R Description The ACST6 series belongs to the ACS/ACST power switch family built with A.S.D. (application Figure 1. Functional diagram specific discrete) technology. This high OUT performance device is suited to home appliances or industrial systems, and drives loads up to 6 A. This ACST6 switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line G transients such as those described in the IEC 61000-4-5 standards. The ACST610 needs COM only low gate current to be activated (I < 10 GT mA) and still shows a high noise immunity complying with IEC standards such as IEC Features 61000-4-4 (fast transient burst test).
