Overvoltage protected AC switch

Key Features

• Benefits

- Enables equipment to meet IEC 61000-4-5

- High off-state reliability with planar technology

- Need no external over voltage protection

- Reduces the power passive component count

- High immunity against fast transients described in IEC 61000-4-4 standards

Description

The ACST12 series belongs to the ACS™/ACST power switch family built with A.S.D.®(application specific discrete) technology. This high performance device is suited to home appliances or industrial systems and drives loads up to 12 A. This ACST12 switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standard. The ACST1210-7 needs a low gate current to be activated (IGT< 10 mA) and still provides a high electrical noise immunity complying with the IEC 61000-4-4 standard. The ACST1235-7 offers an extremely high static dV/dt immunity of 2 kV/μs minimum.
