ACST8308 Datasheet - STMicroelectronics

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 device 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
■ High noise immunity: static dV/dt > 2000 V/µs
■ TO-220FPAB insulated package: 1500 V rms

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 motor of washing machine drum
– Compressor for fridge or air conditioner
