ACST8 Overvoltage protected AC switch Datasheet - production data High off-state reliability with planar technology OUT Needs no external overvoltage protection Reduces the power passive component count High immunity against fast transients G G described in IEC 61000-4-4 standards OUT OUT COM COM TO-220AB TO-220FPAB Applications ACST830-8T ACST830-8FP AC mains static switching in appliance and OUT industrial control systems Drive of medium power AC loads such as: G Universal motor of washing machine drum Compressor for fridge or air conditioner COM 2 D PAK Description ACST830-8G The ACST8 series belongs to the ACS/ACST Figure 1. Functional diagram power switch family built around A.S.D. (application specific discrete) technology. This OUT high performance device is suited to home appliances or industrial systems and drives an induction motor up to 8 A. This ACST8 device embeds a Triac structure with a high voltage clamping device to absorb the inductive turn off energy and withstand line G transients such as those described in the IEC 61000-4-5 standards. COM ACST8 shows a high noise immunity complying with IEC standards such as IEC 61000-4-4 (fast Features transient burst test). Triac with overvoltage protection Table 1.
