ACST8 Datasheet 8 A - 800 V overvoltage protected AC switch OUT TO-220AB G OUT COM G OUT COM TO-220FPAB OUT D²PAK G COM OUT G COM Product status link ACST8 Product summary IT(RMS) 8A VDRM/VRRM 800 V IGT 30 mA Features • Triac with overvoltage protection • High noise immunity: static dV/dt > 2000 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 ACST8 series belongs to the ACS/ACST power switch family built around A.S.D. (application specific discrete) technology. This high performance device is suited to home appliances or industrial systems and drives an induction motor up to 8 A. This ACST8 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. ACST8 shows a high noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).
